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.

- 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.

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.

- mounting diameter: 71 mm

This stage fits the following microscopes:
- Carl Zeiss Jena L-Stativ
- Carl Zeiss Jena Lg
- Carl Zeiss Jena Lu
- Carl Zeiss Jena Lr
- Carl Zeiss Jena Lumipan

This Carl Zeiss Jena stage also fits microscopes:
- Lomo MBI-1
- Lomo MBR-3
- Lomo Biolam
- Lomo sold under the names Bresser and Zenith

If any of the above microscopes currently has a fixed stage (screwed), it is possible to retrofit a holder for interchangeable stages ( like this: https://www.microscopeparts.eu/part/99175) - this applies to both Carl Zeiss Jena and Lomo microscopes.

From the 1930s to approximately the mid-1960s many German manufacturers produced microscopes with the same stage mounting standard, so this stage will also fit them.

How does compatibility of stages between Carl Zeiss Jena and Lomo microscopes work?
- Carl Zeiss Jena stages for L-Stativ microscopes have a mounting diameter of 71 mm
- Lomo stages for MBR-3 / MBI-1 microscopes have a mounting diameter of 73 mm
- The spring-loaded front screw and long side centering screws in the mounting holder compensate for these differences
- Carl Zeiss Jena stages are more solid, heavier, made of brass
- Lomo stages are lighter, made of aluminium with plastic elements

Note that although this is a round and rotating stage, it is not a polarizing stage. It does not have a micrometer scale to read how many degrees (0-360) the rotation has occurred. Without this scale it can of course be used for amateur observations in polarized light, however for professional applications this is disqualifying.

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

- Numerical aperture N.A.: 0,50
- Optical correction: infinity-corrected tube length
- Optical correction class: planachromat
- Cover glass: yes, 0.17 mm
- Thread: M19

Some facts about Carl Zeiss Jena objectives with M19 thread (CZJ M19) and their compatibility with various microscopes from this manufacturer:
- these objectives are most commonly used for technical applications rather than biological applications, therefore most objectives available on the secondary market are intended for use without a cover glass (designation oo/0)
- CZJ M19 objectives intended for biological applications (designation oo/0,17) are most commonly used on Carl Zeiss Jena NU / NU2 microscopes
- in Carl Zeiss Jena Nf and Lumipan microscopes, CZJ M19 objectives are used together with an EPI illuminator
- CZJ M19 objectives can be used in Carl Zeiss Jena Polmi-A microscopes, but they provide a different magnification than the nominal value
- Carl Zeiss Jena Amplival / Amplival Pol / Amplival Interphako / Peraval microscopes feature interchangeable nosepieces, and a dedicated nosepiece for M19-thread objectives was also produced for these microscopes
- Carl Zeiss Jena Metaval and Neophot microscopes use newer versions of CZJ M19 objectives (with a coarse-knurled edge and shiny housing), although many users still experiment with older M19 objectives on these microscopes
- Carl Zeiss Jena Epignost and BK 70x50 microscopes were produced in various versions with completely different configurations - and some of them operate with CZJ M19 objectives
- Carl Zeiss Jena Vertival / Epival / Nf / BK 70x50 microscopes often allow the use of CZJ M19 objectives in EPI dark-field mode
- on the Carl Zeiss Jena Epityp-2 inverted metallurgical microscope, many users employ biological objectives designed for use with a cover glass, placing the microscope slide "upside down", with the cover glass facing downward toward the objective.

Stand family).

The Carl Zeiss Jena Lu microscope features a modular design (the same as the larger Carl Zeiss Jena Nf microscope). This microscope part (this module) consists of the following components:
- dovetail mounting with a clamping screw for attachment to the condenser lifting block
- condenser holder with a retaining screw for securing the condenser
- iris diaphragm (aperture diaphragm)
- iris diaphragm sliding carriage allowing lateral movement of the diaphragm
- eccentric mechanism allowing rotation of the carriage, making it possible to illuminate not only from the sides but also from the front or rear
- spring plate (lock) allowing the entire diaphragm assembly to be moved out of the optical path

The condenser holder has an internal mounting clamp for condensers with a diameter of 39.5 mm.

The movable iris diaphragm mounted below the microscope condenser allows oblique illumination and produces a three-dimensional image effect that increases the contrast of transparent specimens (for example individual unstained cells). This provides an effect similar to Differential Interference Contrast (DIC).

Various names are used on the secondary market for this microscope part, including:
- decenterable iris diaphragm
- decentering aperture diaphragm
- off-axis iris diaphragm
- eccentric iris diaphragm
- sliding iris diaphragm
- sliding iris
- oblique illumination condenser
- condenser with sliding iris
- oblique illumination module
- oblique illumination diaphragm
- offset iris
- Poor Man's DIC device

Note - this condenser module DOES NOT FIT Carl Zeiss Jena Nf, Ng, Lumipan, Polmi-A or Nu microscopes, even though the mounting arrangement appears very similar at first glance.

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".

Mechanically, this condenser is mounted on a dovetail guide located beneath the microscope stage.

Several important notes:
- this pancratic condenser is compatible only with the Carl Zeiss Jena Lumipan microscope
- this condenser is not compatible with the Carl Zeiss Jena Nf or Carl Zeiss Jena Nu / Nu2 microscopes, even though the condenser used in those models is very similar
- this condenser does not include an iris diaphragm because the Carl Zeiss Jena Lumipan microscope has its aperture diaphragm located in the microscope base, directly below the condenser

This condenser is often used as a "donor of parts" for 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 dark-field lens is very often used to build a custom cardioid condenser

All of this allows you to visually confirm that this is exactly the component you are looking for.

Description of this part for the microscope.

the microscope stage:
1. It fastens the stage to the stage holder — that is, indirectly to the microscope stand. This ring has a groove for the spring screw mounted centrally in that holder, as well as two cut-outs at the sides — for the centring screws. It is not, however, a dovetail — in Carl Zeiss Jena L-Stativ microscopes the stage is mounted on a wide ring.
2. Since it is a sliding ring, it is precisely this part that makes it possible to rotate the stage all the way around, even though this is not a polarizing stage.

This is a service part for the repair of a stage in which exactly this element has been damaged. It is not a complete microscope stage.

This ring contains a screw that makes it possible to lock the position, that is, to press the ring tight so that it does not rotate. This screw very often bends completely (for example during transport) or even breaks off. Breakage most commonly occurs when the sliding grease has dried out completely and someone tries to turn the stage by pushing on this screw.

Rotating stages of this kind were used in microscopes of the L-Stativ class, among others:
- Carl Zeiss Jena Lg
- Carl Zeiss Jena Lumipan
- Carl Zeiss Jena Lu
- Carl Zeiss Jena Lr

Remember that microscopes and microscope parts made by the Soviet company LOMO were often clones of Carl Zeiss Jena products. It is therefore possible that this element will also fit a Lomo microscope stage — but the dimensions of this part should definitely be compared very carefully first.

Carl Zeiss Jena produced such stages from the 1930s until roughly the end of the 1960s. During that period minor construction details were changed many times, so it is very important to correctly identify the model of the stage from which this element was removed.

- in the photo gallery a millimetre scale is visible next to every photograph
- the last photographs show a disassembled microscope stage, with an arrow indicating where this element is located in the stage
- the final photographs, in turn, show the complete Carl Zeiss Jena Lg microscope with this stage fitted

All of this makes it possible to confirm visually that this is exactly the element you are looking for.

knobs
- coarse focus mechanism with the rack and control knobs
- microscope base with the rear illuminator port and a decenterable field diaphragm (iris diaphragm)
- stand arm with the microscope head mount and a dovetail guide for the interchangeable objective nosepiece
- dovetail guide with a rack and drive knob, together with the mounting module for a pankratic condenser or a clamp for mounting another condenser.

When can a complete microscope stand be useful?
- if you are building a microscope yourself and selecting every component so that the final configuration is exactly what you need
- if you own an older model (e.g. Carl Zeiss Jena Lg) - replacing the stand acts as an upgrade, while the remaining components are compatible between these models (except for the condenser)
- if your microscope is damaged or in poor condition - in this case the stand simply replaces the damaged microscope component
- if you need to replace only a single component in your damaged microscope (for example the fine focus block or the iris diaphragm), but decide to replace the entire stand instead

Contact us if you are looking for any part to repair a Carl Zeiss Jena Lumipan microscope. Even if the required part is not currently visible in the photographs or has not yet been added to this database as a separate product, it is located inside this complete microscope and is available. Examples include:
- knobs and control knobs
- racks and gears
- guides and shafts
- housing parts
- the iris diaphragm or its individual components
- illumination system components, deflecting mirror
- many other parts, from the complete upper tube down to the smallest screw or spring

The parts listed above are only examples - other components from this microscope stand may also be available.

diameter: 23.2 mm

This eyepiece allows the microscope image to be projected onto a surface such as a wall, ceiling or projection screen.

Originally, this eyepiece model was supplied with the Carl Zeiss Jena Pictoval projection microscope. It can also be installed on virtually any microscope from any manufacturer with a 23.2 mm eyepiece tube.

Important: Projecting a microscope image requires a very large amount of light, so a high-power illuminator is necessary.

Description of this part for the microscope.

head in Carl Zeiss Jena Pictoval projection microscopes (microprojectors). The adjustable tilt angle of the eyepiece tube, which held a projection eyepiece (usually f=100), allowed the position of the projected image on the projection surface to be changed.

Basic parameters:
Manufacturer: Carl Zeiss Jena
Eyepiece mounting diameter: 23.2 mm
Mounting to the microscope arm: 41 mm diameter dovetail ring

Because this microscope head has a Carl Zeiss Jena standard microscope mount (a 41 mm diameter dovetail ring), it can be mounted on most microscopes from this manufacturer (e.g. Carl Zeiss Jena Eduval, Laboval, Ergaval, Amplival, etc.), as well as on microscopes made by Lomo (e.g. Lomo Biolam), IOR and Meopta.

It seems useful to mention a few points:
- never look through this microscope head with the naked eye if a projection eyepiece is installed in it and the head is mounted in a Carl Zeiss Jena Pictoval microprojector. This may result in loss of eyesight due to the very high light output emitted by this microscope
- when mounting this microscope head on a microscope other than a Carl Zeiss Jena Pictoval, a different magnification scale may be obtained than with the original heads designed for the particular microscope model
- projecting a microscope image requires a great deal of light, i.e. a powerful illuminator. This is worth remembering if you intend to use this head to project an image from biological microscopes with standard incandescent illumination (e.g. 15 W 6 V), which is definitely not sufficient
- visual observation using this microscope head may be inconvenient because it has a different (smaller) tilt angle than standard monocular or binocular microscope heads
