have interchangeable objective turrets. This is an excellent solution for storing, using, and quickly replacing entire sets of objectives. For example, you can have separate turrets already equipped with a complete set of objectives:
- 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.

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.

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

Description of this part for the microscope.

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

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).

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.

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.

Description of this part for the microscope.

for taking microscope photographs or recording microscope videos. This is a gray photographic adapter.

Basic technical parameters:
- mounting connection to microscope stand: 41 mm dovetail
- output connection type on the photo port: 49 mm internal thread
- connection for binocular head mounting: Jena standard 41 mm dovetail
- magnification directed to the binocular head: 1.6x
- magnification on the photo output: none (that is 1.0x)

Because this photo head has a 49 mm threaded output, virtually any device, camera, adapter, tube or other accessory can be connected after using an appropriate 49 mm thread adapter. Direct projection technique may be used (because there is no additional optics inside), or any projection eyepieces may be installed in the optical path.

This photographic attachment is intended mainly (but not exclusively) for the following microscope models:
- Carl Zeiss Jena Eduval
- Carl Zeiss Jena Laboval
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival
- Carl Zeiss Jena Vertival
- Carl Zeiss Jena Epival
- Carl Zeiss Jena Metaval
- Carl Zeiss Jena Telaval
- Carl Zeiss Jena Pictoval
- Carl Zeiss Jena Epignost

The list above contains Mikroval series microscopes with gray housings - just like the tube shown and offered here. However, it also works with older black Carl Zeiss Jena microscopes:
- Carl Zeiss Jena L-Stativ (models Lg, Lu and Lr)
- Carl Zeiss Jena Lumipan
- Carl Zeiss Jena Ng
- Carl Zeiss Jena Nf (and NfPk)

Please note that microscopes from other manufacturers also use the 41 / 41.5 mm dovetail connection standard. Because of this, this photographic head can also be used with microscopes made by:
- Lomo (for example Lomo Biolam)
- Meopta
- IOR
- selected Reichert microscopes (for example Reichert Neozet)
- Will Wetzlar
- Hund Wetzlar
- Leitz Wetzlar

This Carl Zeiss Jena tube is also very often used with microscopes having a larger head mounting diameter. In such cases users apply additional spacer or thickening rings. Because of this, this photo adapter also fits microscopes from manufacturers such as:
- PZO (for example the PZO Biolar model with 43 mm connection)
- Olympus (for example the Olympus CH model with 42 mm connection)

The element that allows a photographic camera or imaging camera to be connected to Carl Zeiss Jena Mikroval series microscopes may be referred to by different names. Commonly used names include:
- trino head
- trinocular head
- photo head
- photographic head
- photo attachment
- photographic attachment
- photo adapter
- photographic adapter
- photo tube
- photographic tube
- phototube
- photographic angle tube
- and various combinations of the words head, attachment, adapter or tube with terms such as photo, photographic, for camera and similar

This element is used when the microscope does not have a transmitted light illuminator with a lamp holder installed in the rear part of the base. In such a case, so that there is no open hole and no contamination can enter the inside of the microscope, this opening can be closed with this blanking plug.
When can such a situation occur that the microscope does not have a transmitted light illuminator? Most often when the microscope is intended for reflected light work only and simply does not have any DIA illuminator (transmitted light illuminator).

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

The photo gallery contains detailed photos of this element from different sides, while the video (in the video gallery) shows exactly how this blanking plug is used and where it is mounted.

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.

Magnification: 20x
Field of view: 8
Mounting diameter: 23.2 mm
Designation: PK = plan compensating - recommended for use with plan achromatic objectives, but they also work perfectly with achromatic and apochromatic objectives

Due to their very high quality, these eyepieces are often used together with microscopes from other manufacturers, especially when Carl Zeiss Jena Planachromat objectives are installed.

Important: these eyepieces can be used both with finite tube microscopes (e.g. 160 mm) and infinity-corrected microscopes. This means that they can be used, for example, both on a Carl Zeiss Jena Amplival microscope and on a Carl Zeiss Jena NU-2 microscope.

Note - in my opinion, eyepieces with such a high magnification are recommended rather for "inspection" than for continuous work. I deliberately write "I recommend" because this is my personal opinion based on practical use and not on the manufacturer's documentation.
An eyepiece magnification of 20x should rather be treated as a zoom without revealing additional details (the resolution is not increased). This is important, for example, in heads with built-in magnification (e.g. Carl Zeiss Jena heads with built-in magnification of 1.5x or 1.6x) - when working with a 100x oil immersion objective, we theoretically obtain 100*1.5*20 = 3000x, while physics does not allow the human eye to magnify visible light beyond approximately 1250x - therefore this is a so-called "empty magnification".

of view number: 12
Mounting diameter: 23.2 mm
Designation: PK = plan compensating - recommended for work with planachromatic objectives, but they also work without any trouble with achromats or apochromats

Because of their very high quality they are often used on microscopes from other manufacturers as well, especially when Carl Zeiss Jena Planachromat objectives are mounted in them. The "compatibility" section lists a long series of microscopes these eyepieces fit - but that list is definitely not complete.

Important: these eyepieces work both on microscopes with a finite tube length (160 mm, for example) and on microscopes with infinity optics. That means you can use them on the Carl Zeiss Jena Amplival microscope just as well as on the Carl Zeiss Jena NU-2 microscope.

A note - eyepieces with such a strong magnification are in my opinion better suited to a quick look than to permanent work. I write "in my opinion" on purpose, because this comes from using them and not from the manufacturer's description.
A 16x eyepiece magnification should be treated as a zoom that brings out no additional detail (the resolution is not increased). This matters for example with heads that have their own extra magnification (such as Carl Zeiss Jena heads with a built-in 1.5x or 1.6x factor) - working with a 100x oil immersion objective you then theoretically get 100*1.5*16 = 2400x, while physics does not allow light from the visible range to be usefully magnified for the human eye beyond roughly 1250x - so this is what is called empty magnification.

Inscription: logo "Carl Zeiss Jena" and text "Q1 MADE IN DDR"
Material: aluminium
Length: 52 mm
Width: 14 mm
Mounting: the nameplate is glued on

By default such a nameplate was fitted to most Carl Zeiss Jena microscopes from the Mikroval series onwards. There is also a smaller nameplate - with the manufacturer logo only (without the "Q1 Made in DDR" text). You can see it here: https://www.microscopeparts.eu/part/00604.

Because the adhesive used to attach these plates to the microscope body loses its properties over the years, these plates very often fall off. A nameplate like this makes it possible to restore the factory appearance of a microscope using original parts.
