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.

Note - some models have different dimensions for these screws, for example, longer ones.

Note - older models of the Carl Zeiss Jena Lg microscope use a different screw.

Note - the small screw at the front of this part unscrews in the OPPOSITE direction than most screws, and this is the most common cause of damage.

Note: Please examine the photos carefully. If I have more than one of this part, some of the screws may show traces of improper (forceful) unscrewing. These are not major traces - mostly minor scratches. Of course, they do not affect the functionality of the element at all.

Note - some models have different screw dimensions, for example, longer ones.

Note - in microscopes with a centering stage holder (for polarizing stages), this screw may be different.

Description of this part for the microscope.

This is a component of the transmitted light optical path - it is not a diaphragm for EPI reflected light.

This part fits various Carl Zeiss Jena microscope models built on the Amplival stand:
- Amplival
- Amplival Interphako
- Amplival Pol
- Vertival
- Peraval
- Fluoval
- Docuval

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).

- 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.

- left coarse adjustment knob (macro): 3 pcs. screws 8 mm
- right fine adjustment knob (micro): 1 pc. screw 16 mm
- right coarse adjustment knob (macro): 3 pcs. screws 12 mm

Over the years these plastic knobs are often damaged:
- sometimes they crack due to impact or improper transport securing
- often they are partially melted by a soldering iron, light bulb or even a cigarette
- sometimes they are damaged during attempts to remove them

Manufacturer: Lomo
Magnification: 20x
Model: 20 0.40 P
Numerical aperture: 0.40
Tube length: 160 mm
Focal length: 33 mm
Cover glass: yes, 0.17 mm
Thread: RMS + Pol adapter
Info: P = Polarization

This is an objective designed for transmitted light work with a cover glass.

The RMS thread objective is mounted on a dedicated slide-in adapter that allows it to be used in Lomo MIN series and Lomo Polam series microscopes. Of course, the objective can be unscrewed and another objective can be mounted in the adapter.

The objective itself, once removed from the adapter, is a standard objective that can be used in virtually any microscope with an RMS thread. It is a so-called "short objective" (focal length 33 mm). When a 12 mm adapter is added, the total length becomes 45 mm, allowing it to be used with newer microscopes from any manufacturer.

Lomo polarization objectives with RMS thread can be installed in an RMS-M27 adapter and then used in microscopes such as Lomo Biolam M, Lomo Biolam I, Lomo Lumam, or Lomo ML-2. I have also frequently seen such objectives used in Zeiss Axio series microscopes with M27 thread.

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

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

In summary, this objective is dedicated to Lomo MIN-1, MIN-4, MIN-5, MIN-6, MIN-8, Lomo Polam R-113, Polam L-211, Polam L-213, Polam R-311, Polam LMPR microscopes - but it is practically compatible with any microscope from any manufacturer that supports 160 mm objectives.

Additionally, this objective is very often used for macro photography even without a microscope. This objective does not require a cover glass and works in the "direct-projection" technique, meaning it can be connected directly to a camera without additional optics. This allows achieving a very high magnification scale and great depth of field across the entire image when using focus stacking. The fact that this is a polarization objective (i.e. stress-free optics without internal glass tensions) further improves image quality at high magnifications.

meaning the shaft with focusing knobs mounted on both ends on the sides of the microscope. Part of this shaft contains a toothed rack, or more precisely speaking, it is a toothed shaft. In the item shown and offered here, the fine focus knob (micro focus) is mounted on the left end of the shaft. Please note that the left and right knobs are identical - however, screws of different lengths are used to attach them: the left knob is attached with a 12 mm screw, while the right knob uses a 16 mm screw. Detailed information about the screws used to attach the coarse and fine focus knobs can be found here: https://www.facebook.com/MikroskopyPZO/posts/pfbid0x2tFPHAEqjn4B7BRsvm2vAt9yyuuSM836QS6K4951GqeUFpU2FJH8YXfFFxbz3cPl

Such focus shafts are used in the following microscopes:
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival (and its variants: Fluoval, Epival, Vertival, Interphako)
- Carl Zeiss Jena Metaval
- Carl Zeiss Jena Docuval

This coarse and fine focus shaft may help solve the following problems in Carl Zeiss Jena Ergaval / Amplival microscopes and related models:
- if the shaft became bent, causing a noticeable jump while rotating it (a very common failure)
- if the screw holding the fine focus knob broke off or snapped, leaving part of the screw inside the shaft
- if the left fine focus knob is missing or damaged
- if the thread on the right or left end of the shaft, where the fine focus knobs are attached, is damaged
- if the toothed rack on the shaft (because such a shaft is effectively a toothed shaft) becomes damaged

and related models.

This element is used when transmitted light is temporarily not needed. The illuminator itself does not need to be removed - instead, the light output should simply be completely blocked, and this light output is the collector lens itself. This collector lens is located inside the microscope base, above the angle mirror and below the condenser.

When can there be a need to completely block transmitted light? Most often when:
- a microscope with DIA illumination (transmitted light) and EPI illumination (reflected light) is available, but temporarily only reflected light operation is needed
- a microscope previously working with transmitted light (for example Carl Zeiss Jena Amplival) is being converted into a microscope intended to work permanently only with reflected light (for example converting an Amplival into a Vertival)
- for example a Fluoval microscope is used and it is undesirable that "the lower light is visible"

This element fits the following microscopes:
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival
- Carl Zeiss Jena Epival
- Carl Zeiss Jena Vertival
- Carl Zeiss Jena Interphako
- Carl Zeiss Jena Fluoval
- Carl Zeiss Jena Docuval

Jena
Name: Grossfeld Binocular
Eyepiece mounting diameter: 30 mm
Microscope mount: 41 mm dovetail mount
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.

Amplival microscope
Number of lenses: 3
Numerical aperture N.A.: variable, from N.A. 0.16 to N.A. 1.4
Aperture diaphragm: yes, screwed on as a detachable module

The Carl Zeiss Jena pancratic condenser has three upper lenses:
- for working with low magnification objectives (usually up to 6.3x)
- Apl. 1.4 for working with high magnification objectives
- an oil immersion cardioid darkfield lens with N.A. = 1.05

Mechanically, this condenser is mounted on dovetail rails located on the microscope stage holder block.

Here are the mounting possibilities of the pancratic condenser to Carl Zeiss Jena microscopes:
- to Amplival, Docuval, Epival, Fluoval, Vertival microscopes, this condenser can be mounted directly
- to Ergaval, Nu, Nu 2, Nf microscopes, this condenser is mounted after unscrewing the aperture diaphragm from it
- to Jenaval, Jenapol, Jenalumar microscopes, this condenser can also be mounted, but it is installed together with the entire stage holder block from the Amplival microscope http://www.microscopy-uk.org.uk/mag/artfeb09/rs-jenalumar.html
- be careful, because the Lumipan microscope also features a pancratic condenser, but with a completely different mounting method

This condenser is often used as a "parts donor" for own DIY projects, for example:
- the Apl. 1.4 lens is often used to modify (upgrade) condensers with a lower numerical aperture N.A. in various microscopes
- the darkfield lens is very often used to build a standalone cardioid condenser
- the iris diaphragm has a very wide range of applications

On the last photo, an arrow indicates which element it is and where it is located in the microscope to clearly identify this part. Additionally, the attached video shows how the individual elements of this condenser move.

As far as I know, the same mechanism is used in the following Carl Zeiss Jena microscopes:
- Ergaval
- Amplival
- Fluoval
- Vertival
- Epival
- Docuval
- Metaval
- Peraval

This component is installed onto the shaft by sliding the internal tab into the keyway groove on the shaft. After tightening the round slotted nut, a locking mechanism is created that prevents the nut from loosening on its own due to vibration.

As far as I know, the same mechanism is used in the following Carl Zeiss Jena microscopes:
- Ergaval
- Amplival
- Fluoval
- Vertival
- Epival
- Docuval
- Metaval
- Peraval

This component acts as a resistance regulator and functions as a friction brake. Tightening the outer element compresses the tapered section of the bushing, causing the slotted bushing to contract at the slit. This increases friction on the shaft and makes the entire mechanism move with greater resistance.

Note - in some descriptions available on the Internet, this component is referred to as a "piece of wood".

Jena
Version: grey version, removed from a Carl Zeiss Jena Amplival microscope
Mounting method: aperture diaphragm in the form of a detachable module
Centerable: yes

This iris diaphragm module is mechanically mounted to the bottom of the panchromatic condenser.

In Carl Zeiss Jena panchromatic condensers, the diaphragm is designed as a detachable module because it can be removed and replaced, for example, with a phase contrast module or a polarization module. Precisely because this microscope part can be detached, it is often missing from condensers available on the secondary market - over the years it simply gets lost.

Interestingly, this microscope part is very often modified. When users do not have a phase contrast module or a polarization module, they frequently insert polarizing film or custom-made phase rings into the aperture diaphragm module and obtain the functionality they need through DIY modifications.

This module can also solve a common problem found in Carl Zeiss Jena Amplival microscopes, namely damaged diaphragm blades in the condenser.
