Due to their very high quality, they are often used with microscopes from other manufacturers, especially when Carl Zeiss Jena Planachromat objectives are mounted.

8x eyepieces are best suited for microscopes equipped with a head with a magnification of 1.5x or 1.6x. In such cases, using 10x or higher eyepieces can result in excessive magnification and sometimes poor image quality. In such cases, 8x eyepieces provide the best image and optimal magnification.

Gleitfett grades differ in their parameters.

Gleitfett I E10 and Gleitfett II E75 were supplied with the Carl Zeiss Jena micromanipulator.
The Gleitfett III E410 offered here was supplied with the Carl Zeiss Jena Neophot-21 microscope.

This MAY suggest (although I have no proof in the form of manufacturer documentation) that the lower numbers (I and II) and the lower values of the "E" parameter (E10 and E75) were intended for finer mechanisms - and may therefore have a lower viscosity, for example. The III E410 grease, with its high "E" value, was supplied with a heavy microscope built around massive mechanics - so it may well be thicker.

This grease can of course be used on microscopes from other manufacturers as well - a few are listed in the "compatibility" section, but that is by no means a complete list.

- 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.

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.

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

an incandescent lamp illuminator. This lampholder is not required if you have a microscope with the original halogen illuminator - in that case, the collimator lens is a separate element mounted next to the field diaphragm.

Other used names:
- lamp holder
- lamp tube

- sometimes the German-language term "Lampenhaus" is used

integrated gear for adjusting the height of the microscope condenser, as well as a rack with the element on which the condenser holder is mounted.

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 microscope arm
- 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).

Description of this part for the microscope.

compatible with microscopes designed for a 45 mm parfocal standard It is mounted between the objective and the nosepiece/revolver so that optical focus is maintained despite the additional mechanical extension.

Leitz PLEZY differs from extension adapters available on the market in that it features internal anti-reflective optics, ensuring that despite the mechanical extension of the focal length the image quality is not degraded.

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 parfocal 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 parfocal 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.

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.

There are several models of mechanical microscope stages from Carl Zeiss Jena designed for microscopes of the Mikroval series. They differ mainly in the placement of the control knobs used for movement in both axes, for example:
- the Ergaval model has a short handle with control knobs
- the Amplival model has a long handle
- some variants of the Laboval model had a stage without a handle with control knobs, where the knobs were arranged horizontally on both sides of the stage.

However, many of the individual components used in these stages are identical.

Many of these stages can also be used interchangeably with other microscopes of the Vertival series, which means that many microscopes today no longer have their original stages. For this reason it is best to examine the photos carefully to make sure that the element shown and offered here will fit.

- Carl Zeiss Jena Docuval
- Carl Zeiss Jena NU-2

There are several models of mechanical microscope stages from Carl Zeiss Jena designed for microscopes of the Mikroval series. They differ mainly in the placement of the control knobs used for movement in both axes, for example:
- the Ergaval model has a short handle with control knobs
- the Amplival model has a long handle
- some variants of the Laboval model had a stage without a handle with control knobs, where the knobs were arranged horizontally on both sides of the stage.

However, many of the individual components used in these stages are identical.

Many of these stages can also be used interchangeably with other microscopes of the Mikroval series, which means that many microscopes today no longer have their original stages. For this reason it is best to examine the photos carefully to make sure that the element shown and offered here will fit.

The surface of these microscope stages is often very worn. You could try painting it, but it's definitely better to replace it. The piece I'm showing here isn't perfect - it shows signs of wear, but it's in very good condition.

In the photo gallery there are detailed photos of this element together with the dimensions. Additionally, in the last photo an arrow indicates which element is being referred to and where it is located, in order to clearly identify this part.

The Carl Zeiss Jena Amplival microscope has a modular design and by replacing individual elements it can be converted into other versions based on this platform, e.g. Amplival-Pol, Epival or Vertival.
After replacing the arm from a transmitted light version to one designed for reflected light, it is also necessary to supply light into the arm. This adapter is used for that purpose.
