The device consists of:
- a slot for mounting the illuminator
- the iris diaphragm
- an angled mirror
- a place to insert 32 mm diameter filters

This is an element for repair of a microscope condenser by Carl Zeiss Jena, model Abbe 1.2.
Please note that this is an element (component) for a microscope part (condenser), not for a specific microscope model.

The handle in this ring breaks very frequently, and then the iris diaphragm cannot be opened or closed and the condenser loses its functionality. In such a case, instead of replacing the entire condenser, it is enough to replace only this element - that is, to repair the condenser (recommendation: always repair - never throw away).

Note - over the years Carl Zeiss Jena produced the Abbe 1.2 condenser in different versions, and this ring is available in at least two variants:
- ring with a thickness of 2.5 mm and a handle width of 6 mm
- ring with a thickness of 2 mm and a handle width of 3.5 mm

Here I present and offer a ring with a thickness of 2.5 mm and a handle width of 6 mm. Be sure to check whether this is exactly the ring you need.

The Carl Zeiss Jena BK 70x50 microscope is one of the most versatile small toolmakers microscopes. Its fully modular design and a wide range of accessories allow it to be configured as a workshop microscope, measuring microscope, for Schlieren observation, metallurgical use, or even biological applications. This stage is one of many options for expanding the BK 70x50 microscope.

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).

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 condenser
- replace only the diaphragm
- repair the diaphragm by replacing the damaged blades

monocular (single-eyepiece) PZO MNJ-5 head.

PZO microscope models from the 1950s do not share a common standard for head mounting connectors. However, if the head is not permanently fixed to the microscope, the connector can usually be unscrewed and replaced with another one, allowing the head to be used with microscope models that have a different head mounting interface.

In order to replace the connector in the head, several important conditions must be met:
- the replacement connector must not contain any optical elements
- the replacement connector must have the same thread diameter so that it can be screwed into the head

Basic dimensions:
- internal thread diameter for mounting the connector to the head: 35 mm
- connector diameter at the groove: according to the measurement on the photo, between 31.5 and 32 mm
- connector diameter at the widest point: 34 mm
- diameter of the ring above the connector: 40 mm
- total height of the connector: 35 mm

On the secondary market, it is quite common to find a microscope head with the lower part missing, namely the mounting connector. Why does this happen? Sometimes, when removing the head from the microscope, the user does not realize that it can be pulled out and instead starts unscrewing it. As a result, the head separates from the microscope, but the mounting connector remains in the stand. Such an incomplete head then appears on the secondary market. In this situation, the only way to restore the microscope part to working condition is to add the missing connector element.

This is a service element (repair part) of a PZO MND-5 binocular microscope head. Please note that this is a microscope element (a component) of a microscope part (binocular head) and not a part dedicated to a specific microscope model.

The photos in the gallery show the exact dimensions of the connector described and offered here. In addition, the photos showing the complete head indicate with an arrow which element is being offered and where it is located in the head, so that the part can be clearly identified.

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.

immersion operation and with a phase contrast ring.

Manufacturer: Lomo
Model: APO-WI-F 70x1,23
Magnification: 70x
Numerical aperture: 1,23
Correction: Apochromat
Tube length: 160 mm
Focal length: 33 mm
Immersion: yes - water
Cover glass: yes - thickness from 0.10 to 0.20 mm
Markings: APO = Apochromat, WI = water immersion, F = phase contrast
Thread: RMS
Year of production: 1972

Note: to work in phase contrast technology you need a Lomo KF-4 condenser (you can see it in the database under number 00653).

This is a professional microscope objective with a very wide range of applications. The main features that make this objective exceptional:
- water immersion is preferred by many users over oil immersion
- very high numerical aperture, allowing the objective to produce a high resolution image
- cover glass thickness correction ring

Standard biological objectives are designed to achieve the best image quality when the specimen is located under a cover glass with a thickness of 0.17 mm (hence the marking on objectives such as 160/0.17). Unfortunately inexpensive cover glasses often do not undergo strict production control and a single package may contain cover glasses with thicknesses of 0.14 mm or 0.19 mm, which reduces observation sharpness.
Thanks to the built-in cover glass thickness correction ring (abbreviated CGTCR, CGCC or CGCR) the objective can be adjusted for every specimen so that it operates optimally. This works even when the actual thickness of the cover glass is unknown, because the effect is simply visible and the adjustment can be done "by eye".

Although this objective is a so-called "short" objective, meaning with a focal length of 33 mm, after adding a 12 mm adapter (you can see it in the database under number 99140) it can be used with newer microscopes designed for objectives with a focal length of 45 mm.

The Lomo company produced adapters specifically for these objectives (converters) from RMS thread to M27 thread, which makes them a very attractive option for installation in modern Zeiss Axio series 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.

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

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.

This particular unit was used in a Will Wetzlar V265 microscope.
Objective nosepieces in Will Wetzlar microscopes of the V100, V200 and V300 series have the same construction, and to the best of my knowledge also their equivalents sold by the company Hund Wetzlar - therefore this element should fit all of them.

AO One-Fifty microscopes were sold with one of three types of stages (a photo of a fragment of the manufacturer catalog is included in the image gallery). The simplest model with a square stage did not have a cross movement mechanism for precise specimen positioning, only simple stage clips.

To allow users to expand this microscope, the manufacturer offered an optional cross stage attachment, manufacturer number CAT. 1534 - and this is exactly that attachment.

Basic information:
Item: cross stage attachment for microscope stage
Manufacturer: AO (American Optical)
Catalog number: CAT. 1534
Original catalog name: mechanical stage attachment
For microscope: One-Fifty

At magnifications above 400x, manual manipulation of the specimen slide becomes very difficult. This is exactly why cross stage attachments are used, allowing very precise movement of the specimen at magnifications such as 600x or 1000x with oil immersion.

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

length: (?)
Cover slip: no
Thread: RMS + Pol adapter

This objective is for use with transmitted or reflected light.

This specific item was used with the Lomo MOIN-6 microscope.

The RMS-thread objective is mounted on a suitable sleeve that allows using the objective in Lomo MPD-1 / Lomo MIN-6 / Lomo MIN-8 / Lomo MIN-1 / Lomo Polam microscopes. Of course, the objective can be unscrewed and another objective can be screwed into the sleeve.

The Pol adapter also allows centering the objective relative to the entire optical path - this requires tools (wrenches / tools).

Info: I have repeatedly seen information stating that this RMS-Pol adapter is compatible with Leitz Wetzlar polarization microscopes - but I have not personally checked this.

Description of this part for the microscope.

Specimen holder: no

In the place where stage clips normally hold the microscope slide with the specimen, there is a black matte insert covering the central opening in the stage, which makes it possible to work with reflected light. As visible in the photos and in the video - it can be pulled out, and then it becomes a "normal" stage for work with transmitted light (although of course it lacks the clips that hold the specimen slide).

This particular stage worked in a Hertel & Reuss Metall microscope. YES - "Metall" is the model name and not a statement that the microscope is made of metal. It is the same stage that is used in the Hertel & Reuss Studio II microscope and it can be used on both of these microscopes.
However, it is enough to measure the spacing of the screws that mount the stage to the microscope stand - and if they match - it can also be used with other microscope models.

Hertel & Reuss also produced microscopes that were sold under other brand names, so it is likely that this stage will also fit some microscope models sold under the names:
- Kosmos
- Humboldt
- Beck (CBS Beck Kassel)

Manufacturer name: Epi-Objektiv 18x/0.30 Trockensystem Tubus unendlich, 1940
Name used before 1940: Epi-Objektiv 9.7 Epi, 18 Met Trockensystem Tubus unendlich, 1937
Thread: due to measurement inaccuracy I provide: 11 mm or 11.5 mm
Additional: the objective includes an insert that fits the EPI illuminator
Magnification (so called magnifier magnification): 18x
Numerical aperture: 0.30
Oil immersion: NO (dry objective)
Focal length: 13.8 mm

Compatibility:
- Carl Zeiss Jena EPI reflected light condenser W
- Carl Zeiss Jena EPI reflected light condenser WK
- Carl Zeiss Jena Metalliput metallurgical microscope
- Carl Zeiss Jena Met Mi IX metallurgical microscope

This unusual objective has a narrow special thread, but with the use of an intermediate ring with correction lens it can also be used on a standard microscope stand (e.g. Carl Zeiss Jena Lg).

When this objective is used on the Carl Zeiss Jena Metalliput microscope with an infinity corrected tube (in practice the tube length there is 250 mm), the full magnification of 18x is obtained.
When this objective is used together with a reflected light condenser (with an additional intermediate lens in the tube, that is with a 160 mm tube length) the concave mirrors partially extend under the objective, therefore the free working distance cannot be fully utilized. In such a configuration the real magnification is about two times smaller, approximately 9.7x.

Epi / Met objectives produced in the years 1937-1939 have two numbers engraved on the housing: 9.7 Epi, 18 Met.
a) the smaller value applies when used with the EPI condenser (correction lens focal length = 160 mm)
b) the larger value applies to the magnification obtained when the objective is used with the metallurgical microscope (correction lens focal length = 250 mm).
In 1940 the method of marking magnification on the objective housing was changed and only the "magnifier magnification" and the numerical aperture value were provided.

50x
Thread: RMS
Tube length: 170 mm (?)
Focal length: 37 mm

At that time (most likely in the 1960s) the objectives mounted in microscopes from different manufacturers looked very similar. Many microscope manufacturers ordered objectives from large optics manufacturers (e.g. Leitz Wetzlar) and then only engraved their own names on them. Compare this objective with another one which in the database has number 00618).
Because of this, these objectives can be used with microscopes from many other manufacturers.

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.

Basic information:
Manufacturer: Olympus
Part number in the manufacturer catalogue: AX-RFS
Type of microscope element: field diaphragm with complete mechanical control mechanism
Compatibility: Olympus Provis AX70 and AX80 microscopes
Information: RFS = Reflected Fluorescence System

The modular construction of Olympus AX microscopes allows easy removal and installation of entire microscope elements, but this is often the reason why microscopes appearing on the secondary market are missing some modules.

This is a relatively complex module containing, apart from the diaphragm itself, knobs, control wheels, rods and mechanical gear transmissions. With improper handling or maintenance - and especially with lack of maintenance - this module may become damaged. The most common failures are:
- bending or breaking of the diaphragm blades
- unscrewing and loss of the diaphragm centering screws
- breaking of the knob used to open / close the diaphragm
- breaking of parts of the rotary motion transmission mechanism
