This holder features two centering screws on the side, which are very important for polarization. The front retaining screw is also different from standard microscope stage holders (i.e., those without centering). Of course, standard stages, rectangular, round, and sliding EPI stages can also be used with this holder.

Please note that exactly the same (!) illuminator is also used on the Zeiss Standard / Photomicroscope series microscopes. Please refer to the description of illuminator No. 99684 in this database. YES – these are exactly the same illuminators. However, that particular unit was removed from a Zeiss Photomicroscope II and therefore has its own separate description. You will also find additional photographs and an extended description there.

have an interchangeable objective turret.

This is an excellent solution for owning, using, and quickly replacing entire sets of objectives.

For example, you can have separate turrets already equipped with a complete set of objectives:
- low magnification for observing macro objects with side illumination, without a cover glass (e.g., 2.5x / 3.2x / 5x / 8x / 10x)
- for phase contrast
- for various phase contrasts (positive, anoptral, amplitude, Zernike)
- for DIC
- for water immersion (e.g., Lomo)
- all for oil immersion (e.g., Leitz 10x Oil / 25x Oil / 40x Oil / 100x Oil)
- apochromatic for better color
- for polarization
- only high magnifications, e.g., for analyzing cell wall ornamentation (50x / 63x / 80x / 100x)
- for darkfield work (objectives with an iris diaphragm in the center)

Therefore, having only one microscope we can use it for different purposes and not screw in and unscrew all the lenses manually each time.

a CZJ Ergaval / Amplival microscope with a classic illuminator (6V 15W filament bulb) and simply replacing the bulb holder with the one offered here will create a halogen-illuminated microscope. No.
- the original holder of the "regular" bulb contains a lens that collimates the light beam
- the halogen bulb holder does not contain that lens
- Ergaval / Amplival microscopes designed for halogen illumination have an additional lens threaded into the base

Halogen illumination is (according to many experts) the best microscope illumination because it delivers strong light with a full spectrum, whereas LED often provides only a portion of the color spectrum.

Other used names:
- illuminator
- halogen lamp
- bulb holder

documentation, this element is referred to in German as -Fototubus 100/100 und Tubusträger-.

This is a photographic tube on which a binocular microscope head is mounted - in this configuration it becomes a complete trinocular system. At the top there is an optical output where a camera or photographic device can be mounted.

Basic technical parameters:
- light beam splitting: 0/100 and 100/0
- head mounting method: dovetail 41.5 mm
- mounting method on the photographic port: dovetail 41.5 mm
- internal lens: additional Bertrand lens e.g. for phase contrast adjustment
- extras: slot for installing a filter wheel

Description of this part for the microscope.

a glass frosted filter (so-called ground glass) is located in the optical light beam path. It is mounted on a steel rod ending with a handle positioned outside the microscope base - at the rear, next to the place where the illuminator is inserted. This handle is used to insert and withdraw the frosted filter from the illumination beam path.

This design often leads to damage:
- the glass frosted filter is mounted on the rod in such a way that the glass frequently cracks
- the handle located at the rear of the microscope base very often breaks or crumbles
- the metal rod often jams and as a result of attempts to move it - bends

Here I present and offer this exact frosted filter with the complete movement mechanism:
- glass frosted filter (ground glass)
- holder for mounting the filter to the rod
- all necessary screws to attach this set to the microscope base
- plastic control knob for operating the ground glass

- slot for inserting the illuminator
- angled mirror reflecting the light beam

Important - some versions have a base with a removable illumination collector module with a field diaphragm. This base has this module permanently mounted (screwed), but there is no difference in operation between these versions.

Important - the base does not include the illuminator. The Standard GFL model uses illumination with a 6V 15W bulb mounted in a holder (Lampenfassung). This illuminator is connected to an external transformer. It is a separate component and is not included with the base.

Description of this part for the microscope.

This diaphragm is necessary to set illumination according to the Koehler system.

This element is used in a diaphragm installed in various Carl Zeiss Jena microscope models built on the Amplival stand:
- Amplival
- Amplival Interphako
- Amplival Pol
- Vertival
- Peraval
- Fluoval
- Docuval

The field diaphragm located in the microscope base is part of the transmitted light path - it is not a diaphragm for EPI (reflected) illumination. However, it is VERY LIKELY that individual blades may also fit reflected light diaphragms and other diaphragms (e.g. aperture diaphragms) in Carl Zeiss Jena microscopes and condensers.

Damage to iris diaphragm blades is one of the more common failures in Carl Zeiss Jena microscopes. Most often this occurs when:
- the lubricant in the diaphragm opening / closing mechanism dries out and the user tries to move it by force
- a foreign object gets between the blades (e.g. a glass fragment from a chipped microscope slide)
- the diaphragm is closed too quickly or opened too far

In the event of an iris diaphragm failure, it is possible to:
- replace the entire element (condenser or diaphragm module)
- replace only the diaphragm
- repair the diaphragm by replacing the damaged blades

- and a mounting screw

The mounting screw itself - as a separate component - fits practically most Carl Zeiss Jena microscopes based on the Amplival system:
- Amplival
- Amplival Interphako
- Amplival Pol
- Vertival
- Peraval
- Fluoval
- Docuval

Carl Zeiss Jena developed a complete modular microscope system based on connections made with this type of screw. Thanks to this design, the screw as a service part is also compatible with most accessories, modules and components that can be mounted to the microscope, including:
- EPI arms
- Parktaric Zoom Tube module
- 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 Jenamed microscope is based on mounting screws of a different shape and size (search for it in this database for comparison).

The XY cross mechanism is used for precise movement of the specimen slide on the microscope stage.

Basic versions of Carl Zeiss Jena microscopes are equipped with simple stages with clips that hold the specimen. For this reason, at magnifications above 400x, manual movement of the specimen slide becomes very difficult. This is exactly the purpose of cross stage attachments - to allow very precise movement of the specimen, for example at higher magnifications.

This is not a cheap plastic cross stage attachment - it is a solidly built Carl Zeiss Jena construction, highly sought after on the used microscope market.

Note - if the mounting pin spacing matches, this cross mechanism can be installed on microscope stages of virtually any manufacturer.

Note - Carl Zeiss Jena produced cross mechanisms both with fixed specimen clips and with a spring-loaded clip. The version offered here has fixed clips without a spring.

polarized transmitted light with the possibility of use as a brightfield condenser
Mounting: the condenser is permanently integrated with a dovetail mount
Top lens: flip-out system allowing the upper lens to be moved into or out of the optical path to change the numerical aperture
Iris diaphragm: yes
Diffuser: yes, with the possibility of moving it into or out of the optical path
Polarizer: yes, rotatable, with the possibility of moving it into or out of the optical path

This condenser fits the following Carl Zeiss Jena microscope models:
- Polmi-A
- Nf
- Ng
- Nu / Nu2

Note: despite the visual similarity of the mounting interface, this condenser does NOT fit the Carl Zeiss Jena Lu microscope.

Important: the condenser is permanently integrated with the dovetail mount and cannot be used with other microscopes without significant modifications.

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.
- photo head

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.
- photo head
- trinocular head
- trinocular microscope head
- trinocular head assembly
- photo dome
- inclined tube with photo output

Description of this part for the microscope.

Manufacturer: Carl Zeiss
Name: POL analyzer for simple polarization
Intended for: monocular biological microscopes
Type: for use with transmitted or reflected light

Hinweis: Please check whether the eyepiece diameter is suitable in order to mount the analyzer onto it. The dimensions of the analyzer housing are visible in the photos, and the housing also has a certain tolerance range.

however, no light source is included in the set.
- A stage with top mounting or with side guide rails can be installed on this base
- There is a rack on the stand

This heavy, stable stand is often used for applications completely unrelated to microscopes, for example for mounting drills, lasers or hardness testers.

Fits among others the following Carl Zeiss Jena microscope models:
- Lumipan
- Lg
- Lr
- Lu

Note - production of the L-Stativ series microscopes began before World War II and continued into the 1950s. Over the years, small design details changed, including the method of mounting the microscope head.
- the earliest models had a threaded microscope head, and there was no fixing screw at all
- the latest models already featured an advanced mounting system with a spring screw (you can see it in the database under number 00659)

Note - production of the L-Stativ series microscopes began before World War II and continued into the 1950s. Over the years, small design details changed, including the method of mounting the microscope stage. Microscope models that have a non-removable stage (screwed to the stand) do not have and do not need such a spring screw.

4 mo2 condenser holder that was used in the Carl Zeiss Jena Ergaval microscope. The same condenser (but with a different lower lens) is used in an identical holder in Fluoval microscopes. Condenser holders with such screws can also be found in the following microscopes:
- Docuval
- Amplival
- NU-2

The purpose of this spring screw is to push the clamp in which the condenser is mounted outward. Thanks to the spring integrated in the screw, it is possible to center the condenser using long centering screws (you can find such a centering screw in the database under number 99132).

In the last photo, an arrow clearly indicates which screw is meant and where it is mounted in the condenser holder.

- knobs operating the internal mechanism
- gear assembly forming the fine focus mechanism (it can be removed because it is a replaceable microscope element)

The entire block fits the Carl Zeiss Jena Lg microscope (from the L-Stativ group), however the fine focus mechanism inside can be unscrewed and as far as I know (to the best of my knowledge) it also fits the microscopes:
- Carl Zeiss Jena Lr
- Carl Zeiss Jena Lu
- Carl Zeiss Jena Lumipan

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.
