Description of this part for the microscope.

This mounting screw fits most Carl Zeiss Jena microscopes of the CF250 series:
- Jenamed
- Jenaval
- Jenalumar
- Jenapol
- Jenatech
- Jenavert

Carl Zeiss Jena developed a complete modular microscope system based on connections using this type of screw. Therefore, this screw as a service part is also compatible with most accessories, modules and microscope elements that can be mounted to the microscope, including:
- magnification changers
- VIS analyzers
- trinocular heads
- Interphako heads

Important - carefully check the shape and dimensions of the screw to make sure it is the size you need. For example, the modular design of the Carl Zeiss Jena Amplival microscope is based on mounting screws of a different shape and size (search for it in this database to have a comparison).

Jenalumar 50

Please note the following:
- both microscopes listed here use this illuminator for EPI fluorescence, i.e. reflected light. This is not transmitted-light fluorescence.
- this illuminator requires a Carl Zeiss Jena SH 50 power supply for operation
- the Carl Zeiss Jena Jenalumar microscope was produced in two variants - this illuminator fits the Jenalumar version with two small, separate illumination modules
- information can be found on the Internet claiming that this illuminator is suitable for Carl Zeiss Jena Jenavert microscopes. This is NOT correct.
- an HBO lamp is not the same as an XBO lamp.
- Jenamed microscopes other than the "Fluorescence" version have a differently mounted head and this illuminator CANNOT be installed on them.

Important - operating used, overheated HBO lamps, lamps with unknown operating time or from an uncertain source may result in explosion, damage to the illuminator, contamination of the room and a risk to the user's life and health. For this reason, this illuminator DOES NOT INCLUDE a light source (i.e. it does not include the HBO mercury burner).

molded parts of Carl Zeiss Jena carry their own numbers. This microscope element bears the number 2580 (full designation: Si10 CZ 2580).

This is a service element (replacement part) for the trino head (head with photo output), suitable for Carl Zeiss Jena CF-250 microscopes. Please note that this is a microscope element for a microscope part (the trinocular head) and not a part for a specific microscope model.

Carl Zeiss Jena CF-250 microscopes have a modular design, and the microscope part to which the eyepieces are mounted (commonly referred to as the "head", "binocular" or "binocular tube") is a separate element from the angled tube (sometimes the German term "Winkeltubus" is used). If the angled tube has a photographic output, it is referred to as a "Fototubus". It is precisely for this microscope part that the upper main part of the housing is offered and described here.

Note - although the Carl Zeiss Jena Jenapol and Jenatech microscopes also belong to the CF-250 series, they have a differently constructed photographic output and this housing DOES NOT FIT them.

The exact dimensions of the described and offered microscope element can be seen in the gallery photos. Additionally, in the last photo an arrow indicates which element is being referred to and where it is located in the head, in order to clearly identify this part.

Many different names are commonly used for the trino head. It is worth listing them here - each of them refers to the same microscope part.

Metal, cast or injection-molded parts manufactured by Carl Zeiss Jena have their own identification numbers. In this mechanism the lens is mounted on a cast part marked with number 2582 (full marking: Si10 CZ 2582).

This is a service element (repair part) of the trinocular head (photo tube), suitable for Carl Zeiss Jena microscopes of the CF-250 series. Please note that this is an element (component) of a microscope part (German: "Fototubus") and not a part dedicated to a specific microscope model.

Carl Zeiss Jena microscopes of the CF-250 series have a modular design and the microscope part to which the eyepieces are mounted (commonly referred to as "head", "binocular" or "twin tube") is a separate element from the angle tube (sometimes the German term "Winkeltubus" is used). If the angle tube has a photographic output, it is referred to as a "photo tube". The Bertrand lens offered and described here is intended specifically for this microscope part.

Hinweis - Carl Zeiss Jena microscopes Jenapol and Jenatech, although they also belong to the CF-250 series, have a differently designed photographic output and this mechanism DOES NOT FIT these models.

Hinweis - Carl Zeiss Jena also produced a simplified version of the photo tube which does not contain a Bertrand lens inside. In the image gallery there is also a page from the manufacturer's catalog so that it is visible whether these versions differ externally in appearance. This Bertrand lens shown and offered here CANNOT be installed in such a simplified version of the photo tube.

The photos visible in the gallery show the exact dimensions of the element described and offered here. Additionally, in the last photo an arrow indicates which element is concerned and where it is located in the head, in order to clearly identify this part.

In common usage many names are used for the photo tube. It is worth listing them here - each of them refers to the same microscope part.

allows correction of vision in one eye and proper adjustment of image focus.

Basic parameters:
- Type: tube with diopter correction ring
- Diameter of supported eyepieces: 30 mm
- Color: white

Fits 30 mm heads used, among others, in the following Carl Zeiss Jena microscopes:
- Carl Zeiss Jena Jenamed
- Carl Zeiss Jena Jenalab
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenatech
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenavert

Some Carl Zeiss Jena Jenalab and Jenamed microscopes (for example the Jenamed Fluorescence) were factory-equipped with binocular heads accepting 23.2 mm eyepieces. In that case this end cap is **not** compatible with that binocular head. By "that" I specifically mean the binocular head, as this is a component of the head rather than of the microscope itself.

Interestingly, 30 mm wide-field binocular heads are also occasionally fitted to older microscopes from the Mikroval series (for example Ergaval and Amplival). When combined with GF-Planachromat or GF-Planapochromat objectives (the latter also used on the Docuval), this provides arguably the best optical combination available for Carl Zeiss Jena microscopes with a 160 mm tube length.

250 series microscopes.
Note that this element is a component of a microscope element (the angled tube) and not a part dedicated to a specific microscope model.

This element fits, among others, the following Carl Zeiss Jena microscopes from the CF-250 series:
- Jenamed
- Jenaval
- Jenalumar
- Jenavert
- Jenatech
- Jenapol

Important: the element DOES NOT INCLUDE the screw used to secure the microscope head.

Inside this element there is a protective glass (without its own magnification, so called "zero lens") with a violet anti-reflection coating.
Although this holder for the binocular microscope head and the holder located at the photographic port look the same, have the same dimensions and are mechanically compatible - they are NOT (!) identical.
- the binocular microscope head mount contains a protective glass with a violet anti-reflection coating
- the mount located at the photographic port contains a protective glass with a green anti-reflection coating.

The photos visible in the gallery show the exact dimensions of the element described and offered here. Additionally, in the last photo an arrow indicates which element is being referred to and where it is located in the microscope head, in order to clearly identify this part.

- Carl Zeiss Jena Jenalab

Interestingly, binocular heads with a 30 mm eyepiece mounting diameter are sometimes also installed in older microscopes of the Mikroval series (e.g. Ergaval and Amplival) - in such cases this eyepiece will also fit them, because - in general - eyepieces fit the head mounted on the microscope, not the microscope itself.

A single Carl Zeiss Jena PW 6.3x (25) eyepiece can solve the following problems:
- a second 6.3x eyepiece is missing to complete a pair
- a low magnification eyepiece is needed for use in a trinocular photo tube

New (usually Chinese) microscope filters are sometimes not even made of glass. And even if they are made of glass - you may encounter scandalous examples where the glass is only surface-colored. Unfortunately, cheap colored glass filters may not be internally homogeneous and can cause light refraction distortions.

This filter set by PZO was originally sold together with the PZO Biolar microscope. It was manufactured in the 1970s (and certainly before 1977), so these are optical glasses that are about half a century old! They have never been used until now (this is so-called NOS - New Old Stock), therefore these are excellent old-class optical glasses of the highest quality.

Filters with a 32 mm diameter are used - and can be used - in microscopes from various manufacturers:
- Carl Zeiss Jena
- Zeiss West Germany
- Eschenbach
- Meopta
- Nikon
- ROW
- Leitz Wetzlar
- Wild
- Hund
- Kosmos
- and many others

Important - popular microscopes by Lomo (for example Lomo Biolam) have a 33 mm filter holder, so the filters shown here have too small a diameter and may fall out from some Lomo holders.

Diopter adjustment: yes, for one eyepiece

The set also includes two eyepieces:
- Model: Carl Zeiss Jena GF-Pw 10x (25)
- Mounting diameter: 30 mm

This head is most commonly used in the following microscopes:
- Carl Zeiss Jena Jenamed
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenapol
- Carl Zeiss Jena Jenvert
- Carl Zeiss Jena Jenatech
- Carl Zeiss Jena Jenalab

Interestingly, widefield binocular heads with a 30 mm eyepiece mounting diameter are sometimes also installed in older Mikroval series microscopes (for example Ergaval and Amplival). If the microscope is additionally equipped with GF-Planachromat series widefield objectives (or GF-Planapochromat objectives used in Docuval microscopes) - this creates the best possible combination for Carl Zeiss Jena microscopes with a 160 mm tube length.

This microscope head model is identical to the Baader Mark V binocular viewer used in astronomical telescopes and is often purchased by astronomy enthusiasts and adapted for telescope mounting.

Jenamed Cytology
- Jenamed Hematology
Carl Zeiss Jena Jenamed 2 and Jenamed Histology microscopes already use different stages.

This particular example shown and offered here was removed from a Carl Zeiss Jena Jenamed Cytology microscope.

The stage in Carl Zeiss Jena Jenamed microscopes is a flat, smooth surface permanently attached with screws to the microscope body, onto which cross table mechanisms or specimen holders are mounted - various versions depending on individual needs.

Mechanically, this stage consists of two elements:
- a smooth upper steel surface attached to the cast form underneath
- the lower cast form (with manufacturer number), which is attached to the microscope body
Both parts have an opening for the microscope condenser. The condenser is mounted from the underside of the stage (condenser available separately).

Metal cast or injection-moulded microscope parts made by Carl Zeiss Jena have their own numbers. This part carries the number 2712 (full marking: Si10 CZ 2712).

In the last photo I indicate with an arrow exactly which element it is and where it is located in the microscope.

microscope. It will most likely also fit other models from the Jenamed series (e.g. Jenamed Variant, Jenamed Fluorescence, Jenamed-2, Jenamed Hematology). Please note however that the Carl Zeiss Jena Jenamed Histology microscope is factory-equipped with a different type of condenser - the "flip-out" type.

To make sure whether this condenser will fit a specific Carl Zeiss Jena microscope from the Jenamed series, it is best to carefully check all dimensions based on the gallery photos or ask a question on a professional forum, e.g. https://www.mikroskopie-forum.de/

Mechanically, this condenser is mounted from the underside of the microscope stage - first it is screwed into the threaded opening in the stage and then secured with three screws. The upper lens can be unscrewed to obtain a condenser with a lower numerical aperture N.A. This condenser does not have an iris diaphragm installed because in Jenamed microscopes it is a separate element.

Replacing the condenser in a Carl Zeiss Jena Jenamed microscope may be necessary:
- when the upper lens becomes damaged, for example when it turns matte due to exposure to various chemical reagents
- when the upper lens becomes damaged due to rubbing. Surprisingly, this unusual type of damage is very common after several decades of microscope use.

In the last photo I indicate with an arrow exactly which element it is and where it is located in the microscope.

was removed from a Carl Zeiss Jena Jenamed Cytology microscope. It will most likely also fit other models from the Jenamed series (e.g. Jenamed Variant, Jenamed Fluorescence, Jenamed-2, Jenamed Hematology).

It does not fit the Jenamed Histology model because the Carl Zeiss Jena Jenamed Histology microscope features a different type of condenser (a 'flip-out' type) by default. For this reason, the iris diaphragm is located slightly lower than in other models and is different.

To make sure whether this iris diaphragm will fit a specific Carl Zeiss Jena microscope from the Jenamed series, it is best to carefully check all dimensions based on the gallery photos or ask a question on a professional forum, e.g. https://www.mikroskopie-forum.de/

Mechanically, this diaphragm is mounted underneath the condenser. The entire diaphragm module is attached to the microscope body with four screws. It is not mechanically connected to the condenser - these are separate elements. The lever pin used to open / close the diaphragm protrudes through a special opening at the front of the microscope, making it possible to adjust the diaphragm opening. This opening is located in the cover of the filter wheel - here one can see further relationships between the individual elements of the light path.

Carl Zeiss Jena Jenamed microscopes do not have a field diaphragm.

Replacement of the aperture diaphragm module in a Carl Zeiss Jena Jenamed microscope may be necessary:
- when some of the iris diaphragm blades become damaged (bent or broken)
- when the lever used to open / close the diaphragm breaks off
- when the teeth of the gear wheel mounted in this module become damaged

Metal cast or injection-moulded microscope parts made by Carl Zeiss Jena have their own numbers. This part carries the number 2713 (full marking: Si10 CZ 2713).

This knob features the characteristic white cap used on Carl Zeiss Jena microscopes, which is often lost during decades of microscope use.

Mechanically, this knob is attached to the potentiometer. The fixing screw is covered by a white metal cap.

The function of this element is to reflect light coming from the microscope base vertically upwards so that, after passing through the microscope slide with the specimen and the objective, it reaches the eyepieces and ultimately the user's eyes.

Metal cast or injection-moulded parts made by Carl Zeiss Jena have their own numbers. This part carries the number: 2721 (full marking: Si10 CZ 2721).

Replacement of the angle mirror in Carl Zeiss Jena Jenamed microscopes may be necessary in the following cases, among others:
- if the mirror becomes significantly scratched as a result of improper cleaning (minor scratches are usually not visible during normal use)
- if the reflective silver coating of the installed mirror becomes oxidised
- if the mirror becomes damaged, chipped or cracked, for example after coming loose from its mount

attached to the microscope stand with screws. It serves as a mounting platform for mechanical stages, XY stage mechanisms, or specimen holders - various versions depending on the user's requirements.

Mechanically, this stage consists of two elements:
- a smooth upper steel plate attached to the cast component below
- a lower cast component (with the manufacturer's part number) attached to the microscope stand
Both parts have an opening for the microscope condenser. The condenser is mounted from below the stage (condenser available separately).

Metal cast or injection-moulded microscope parts manufactured by Carl Zeiss Jena carry their own part numbers. This part is marked with number 2712 (full marking: Si10 CZ 2712).

This microscope stage DOES NOT FIT the following Carl Zeiss Jena microscopes:
- Jenamed 2
- Jenamed Variant
- Jenamed Cytology
- Jenamed Hematology
- Jenamed Fluorescence

More precisely: the lower part (marked Si10 CZ 2712) is identical to the one used in other Jenamed microscope models (except Jenamed-2), whereas the smooth upper steel plate used in the Jenamed Histology differs from those used in other models by the size of the condenser cut-out (opening).

In the last photo, I indicate with an arrow exactly which component is being offered and where it is located within the microscope.

Mechanically, this diaphragm is mounted below the condenser. The complete diaphragm module is attached to the microscope stand with two screws. It is not mechanically connected to the condenser - these are separate components. The lever (pin) used to open and close the diaphragm extends through a dedicated opening at the front of the microscope, allowing adjustment of the diaphragm opening.

Carl Zeiss Jena Jenamed microscopes do not have a field diaphragm.

Replacement of the aperture diaphragm module in a Carl Zeiss Jena Jenamed Histology microscope may be necessary:
- when one or more iris diaphragm blades become damaged (bent or broken)
- when the lever used to open and close the diaphragm breaks off
- when the teeth of the gear wheel installed in this module become damaged

Metal cast or injection-moulded microscope parts manufactured by Carl Zeiss Jena carry their own part numbers. This part bears number 2714 (full marking: Si10 CZ 2714). The iris diaphragm module used in the other Carl Zeiss Jena Jenamed microscope models bears part number Si10 CZ 2713.

therefore cannot be used in:
- Jenamed Cytology
- Jenamed Variant
- Jenamed Hematology
- Jenamed Fluorescence
- Jenamed-2

Mechanically, this condenser is a "flip-out" design and is mounted in a metal frame together with a lever used to rotate it in order to obtain one of two operating modes: low or high numerical aperture N.A. This lever extends outside the microscope housing so that the user can operate it.

The complete module is mounted underneath the microscope stage by attaching the entire condenser assembly from below with four screws. This condenser does not contain an iris diaphragm because, in Jenamed microscopes, it is a separate component mounted beneath the condenser.

In the Carl Zeiss Jena Jenamed Histology microscope, this condenser is not used together with the wide-field lens that is installed beneath the condenser in other Jenamed models (part Si10 CZ 2711-1). In the Jenamed Histology model, a polarizer is installed in this position instead.

Replacement of the condenser in a Carl Zeiss Jena Jenamed Histology microscope may be necessary:
- when the upper lens becomes damaged, for example by becoming cloudy due to exposure to various chemical reagents
- when the upper lens is damaged by friction. Surprisingly, this unusual type of damage is very common after several decades of microscope use
- when the mechanical lens switching mechanism ("flip-out") becomes damaged

Metal cast or injection-moulded microscope parts manufactured by Carl Zeiss Jena carry their own part numbers. This condenser module bears number 2713 (full marking: Si10 CZ 2713).

In the last photograph, I indicate with an arrow exactly which component is being offered and where it is located within the microscope.

2 Fluorescence

It DOES NOT FIT Carl Zeiss Jena microscopes from the Jenamed series and therefore cannot be used in:
- Jenamed Cytology
- Jenamed Variant
- Jenamed Hematology
- Jenamed Histology

Mechanically, this condenser is mounted on the microscope stage support plate (stage support). The microscope stage is installed onto this support plate together with the condenser. The upper condenser lens can be unscrewed - after removing it, the condenser operates with a lower numerical aperture N.A.

This condenser does not contain an iris diaphragm because, in Jenamed microscopes, it is a separate component mounted beneath the condenser.

Replacement of the condenser in a Carl Zeiss Jena Jenamed-2 microscope may be necessary:
- when the upper lens becomes damaged, for example by becoming cloudy due to exposure to various chemical reagents (common in fluorescence applications)
- when the upper lens is damaged by friction. Surprisingly, this unusual type of damage is very common after several decades of microscope use

Metal cast or injection-moulded microscope parts manufactured by Carl Zeiss Jena carry their own part numbers. The microscope stage support plate on which the condenser is mounted bears number 3030 (full marking: Si10 CZ 3030).

Jenamed Cytology
- Jenamed Hematology
- Jenamed Histology
- Jenamed-2
- Jenamed Fluorescence

This is a microscope element placed in the microscope base. It transmits the light beam from the illuminator, unifies it (blurs the filament image using a diffuser), and then properly focuses it using a collimating lens. The light beam prepared in this way then hits an angular mirror (this is a separate element).

This microscope part is known on the secondary market among DIY enthusiasts creating their own optics projects and is frequently used by them.

Description of this part for the microscope.

Jenamed Variant
- Jenamed Cytology
- Jenamed Hematology
- Jenamed-2
- Jenamed Fluorescence

Important: this element is not used in the Jenamed Histology model. In this microscope version, a flip-out type condenser is used, and instead of the wide-field lens there is a polarizer. In other words - this element does not fit the Carl Zeiss Jena Jenamed Histology microscope.

This lens enables uniform illumination of the specimen when working with low magnification objectives. It is most commonly used with 3.2x and 5x objectives. It is an element installed in the microscope base and is part of the transmitted light illumination system.

Mechanically, this lens has a pin that extends outside the housing so that the user can insert or remove the lens from the optical path. It is mounted below the condenser aperture diaphragm. In Jenamed microscopes, the condenser, the aperture diaphragm, and this wide-field lens are all separate modules.

Metal cast or injection-moulded microscope parts manufactured by Carl Zeiss Jena carry their own part numbers. This condenser module bears number 2711-1 (full marking: Si10 CZ 2711-1).

following Carl Zeiss Jena microscopes:
- Jenamed Variant
- Jenamed Cytology
- Jenamed Hematology
- Jenamed Histology

This is a large module that is mechanically integrated, although it can be disassembled into smaller parts. However, if replacement becomes necessary, it is usually more convenient to replace the complete assembly. For this reason it is presented and offered here as a complete unit.

The assembly shown here includes:
- internal power supply electronics (potentiometer, transformer, etc.)
- fine focus mechanism (micro-adjustment)

If you need any individual component from this assembly, for example the transformer, a specific electronic board, only the brightness control potentiometer, or only the fine focus mechanism itself, please contact us by email.

Please note:
- the power supply is compatible with every Carl Zeiss Jena Jenamed microscope model, including Jenamed 2 and Jenamed Fluorescence
- however, the complete fine focus mechanism assembly does NOT fit Jenamed-2 and Jenamed Fluorescence, although some smaller components of the fine focus mechanism are identical across all Jenamed microscope models

This complete assembly may be required to solve, among others, the following problems in Carl Zeiss Jena Jenamed microscopes:
- when the microscope illumination does not work due to a defective power supply. This may be caused by mains voltage surges, ageing electronic components, or damage resulting from improper modifications (for example LED conversions)
- when the illumination works but brightness adjustment does not function because of a defective or worn potentiometer
- when the fine focus mechanism does not work properly, for example when the objective turret does not move upward or slowly drops by itself

It is very important to note that the internal power supply used in Carl Zeiss Jena Jenamed microscopes converts 220-240V mains voltage to 6V with a maximum power output of 25W. This power supply has the same specifications as those used in Carl Zeiss Jena Jenaval and Carl Zeiss Jena Jenalumar microscopes. If you own one of these microscopes with a defective power supply, any qualified electronics technician can transfer the electronics from a Jenamed microscope.

for microscope slides. It allows quick insertion and replacement of slides without the use of an XY mechanical stage.

Several different specimen holding systems are found in Carl Zeiss Jena microscopes. The slide cassette system is one of them and represents an alternative to traditional designs using a mechanical stage and slide-retaining clips.

Various names are commonly used for this specimen holder, including:
- slide cassette (German: Gleitkassette)
- specimen cassette (Ger.: Objektkassette)
- microscope specimen cassette
- specimen holder
- slide holder

This is not a complete stage-mounted system and therefore it is not a "slide cassette system". It is only the cassette itself (slide cassette), which is a replaceable wear item installed into the appropriate carrier assembly.

In the last gallery photograph, I indicate the exact component being offered with an arrow.

objective nosepiece. It consists of slots (empty openings) into which filter sliders are inserted. This is the component that the Microscopy-UK portal (https://www.microscopy-uk.org.uk/mag/imgmar09/JenamedFinal.pdf) referred to as "in-tube filter holders".

This filter holder is compatible with the following Carl Zeiss Jena microscopes:
- Jenamed Variant
- Jenamed Cytology
- Jenamed Hematology
- Jenamed Histology
- Jenamed-2
- Jenamed Fluorescence

Metal, cast, and injection-moulded parts manufactured by Carl Zeiss Jena have their own identification numbers. This part bears the number: 2709/2 (full designation: Si10 CZ 2709/2).

Mechanically, this "block with empty slots" is attached to the casting numbered Si10 CZ 2708, which is the objective nosepiece block.

In the last photo of the gallery, I use an arrow to show exactly which component is being described.

Carl Zeiss Jena, PZO, Meopta, Olympus, IOR and others.

This tube makes it possible to connect a camera or photographic camera to a trinocular head or directly to the microscope body, even when no trinocular head is installed.

Originally, this adapter was designed for the Lomo TRN-1 trinocular head. This head was used in Lomo Polam polarizing microscopes from the early 1970s onwards.

Several remarks regarding the model designation of the trinocular head for which this component was originally intended:
- the name Lomo TRN-1 is the Latin alphabet designation. In Cyrillic script the model designation appears as TPH (for example model TPH1Y4.2), and this designation is used in the manual for the Lomo Polam L-211 microscope
- the vast majority of these trinocular heads are not marked with any model designation
- the Envirotools website http://www.envirotools.hu/ateso_fenyu_polarizacios_mikroszkop.htm refers to this trinocular head as HU-POL

In the last photograph, an arrow indicates exactly which component is being offered and where it is located in the Lomo Polam microscope, allowing this part to be identified unambiguously.

Basic technical parameters of this tube:
Mounting method to the trinocular head or microscope: 41 mm dovetail mount (this is also the Carl Zeiss Jena standard)
Camera mounting method: male M39 thread
Alternative camera mounting method: since the M39 thread can be removed, a plain smooth tube with a diameter of 35 mm remains
Additional optics: yes, the original optics are installed inside, although they can be removed, leaving only an "empty tube".

This is not "a tube dedicated to a specific microscope model". It is a tube originally mounted on the third port (photo port) of a trinocular head. Since a trinocular head can be installed on microscopes other than the model with which it was originally supplied, this tube can be regarded as a universal accessory.

These technical parameters make it possible to use this tube with virtually any microscope manufactured by:
- Lomo (for example Biolam, Polam, MBB-1A and others)
- Carl Zeiss Jena (for example Ergaval, Amplival, Jenamed and others)
- IOR, Meopta and other manufacturers using a 41 / 41.5 mm dovetail mount

In addition, a 41 mm dovetail tube can easily be mounted on microscopes equipped with a 42 mm or 43 mm opening, for example:
- Olympus (for example CH, CH-2, BH-2 models)
- PZO (for example Biolar, Studar, MB-30 and others)

The entire list of microscope manufacturers and models given above may also be treated as a list of microscopes compatible with the Lomo TRN-1 trinocular head. Indeed, many examples can be found on the Internet showing this head being used with microscopes made by manufacturers other than Lomo.

Because this tube is equipped with an M39 thread by default, almost any camera or photographic camera can be attached by means of a suitable adapter, for example:
- devices with M42 threads
- devices with C-mount threads
- Nikon, Sony, Olympus and other camera standards

This is therefore a universal photo tube featuring a 41 mm dovetail on one side and either an M39 thread or a 35 mm tube on the other side.

In the image gallery, every photograph includes a millimetre scale, and in addition, the dimensions of the dovetail, tube and thread have been measured with calipers so that compatibility can be determined precisely.

Description of this part for the microscope.

Carl Zeiss Jena microscope heads with a wide field of view (German: Grossfeld) have one eyepiece tube with diopter adjustment and a second one without it. Here I present the tube without diopter adjustment (straight eyepiece tube).

Basic parameters:
- Type: straight eyepiece tube
- Compatible eyepiece diameter: 30 mm
- Colour: white

Compatible with 30 mm microscope heads used, among others, in the following microscopes:
- Carl Zeiss Jena Jenamed
- Carl Zeiss Jena Jenalab
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenatech
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenavert

Some Carl Zeiss Jena Jenalab and Jenamed microscopes (for example the Jenamed Fluorescence) were factory-equipped with binocular heads accepting 23.2 mm eyepieces. In that case this end cap is **not** compatible with that binocular head. By "that" I specifically mean the binocular head, as this is a component of the head rather than of the microscope itself.

Interestingly, 30 mm wide-field binocular heads are also occasionally fitted to older microscopes from the Mikroval series (for example Ergaval and Amplival). When combined with GF-Planachromat or GF-Planapochromat objectives (the latter also used on the Docuval), this provides arguably the best optical combination available for Carl Zeiss Jena microscopes with a 160 mm tube length.

The last photo in the gallery shows a complete microscope head. An arrow indicates exactly which component is being described and where it is located inside the head, making it easy to identify.

Carl Zeiss Jena wide field microscope heads (those designed for 30 mm eyepieces) have two such components (two prism covers). They protect the prisms of the right and left eyepieces. Both covers are identical and interchangeable, so there is no constructional difference between the right-hand and left-hand cover.

This is a component for a microscope head, not for a specific microscope model.

This component fits microscope heads designed for 30 mm eyepieces used, among others, in the following microscopes:
- Carl Zeiss Jena Jenamed
- Carl Zeiss Jena Jenalab
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenatech
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenavert

The Carl Zeiss Jena wide-field binocular head for 30 mm eyepieces is mechanically the same device as the Baader Mark V binocular viewer used with astronomical telescopes. They are based on the same binocular head; the Baader Mark V differs only in having a modified mounting interface, astronomical eyepiece adapters and, in some versions, different external markings. Consequently, the component offered here is also compatible with the Baader Mark V binocular viewer.

Metal cast or injection-moulded components manufactured by Carl Zeiss Jena have their own part numbers. This component is marked with the number 2630 (full designation: Si10 2630 / Si10 CZ 2630). In addition, the number "1" or "2" appears next to the part number to indicate whether it is the cover for the right-hand or left-hand prism. This is the only difference, because mechanically the right-hand and left-hand covers are identical.

This is a component of the binocular head rather than a component dedicated to a particular microscope model.
