Description of this part for the microscope.

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.

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

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

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).

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

millimeter scale.

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.

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

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.

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.

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 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.

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.

objective
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.
