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).

10 160/-
Color correction: Planachromat
Numerical aperture: 0.10
Tube length: 160 mm
Focal length: 45 mm
Cover glass: no
Immersion: no
Thread: RMS

This lens provides an excellent, wide image, and because it doesn't require a cover glass, it's often used for macro photography and stacking.

Important - this lens is not suitable for taking photos using the "direct-projection" technique, as it requires plan-compensation optics.

A microscope objective with such low magnification is used, among others, in the following fields:
- tissue overview examination in pathomorphology
- observation of insects
- observation of minerals
- observation of inclusions in amber
- handwriting analysis
- observation of micromollusks
- and many others

It can be used with any microscope from any manufacturer. Of course, the microscope must be compatible, i.e. support RMS objectives, TL=160 mm, FL=45 mm.

Focal length: 45 mm
Cover glass: no
Immersion: no

This is one of the most commonly used microscope objectives for macro photography and focus stacking.

Important - this objective IS SUITABLE for taking images using the "direct-projection" technique, as it does not require plan-compensating optics.

It can be used with any microscope from any manufacturer. Of course, the microscope must be compatible, meaning it supports RMS objectives, TL=160 mm, FL=45 mm.

On a mechanical microscope stage there are two such clamps, between which a microscope slide with a specimen is placed. These clamps - right and left are not identical. Here I present and offer the left clamp, which does have a spring.

Note - different stage models use different clamps. In the photo gallery there are detailed photos of this element along with dimensions. In the last photo, the stage to which this clamp fits is shown. Additionally, an arrow indicates where this element is located, so it is clear which part of the microscope stage is being referred to.

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

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.

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.
