Description of this part for the microscope.

33 mm
Cover Glass: 0.17 mm
Immersion: Yes, oil immersion
Thread: RMS
Info: Ph = phase contrast. NOTE - this is not a "Phv" type contrast.

This objective lens is in excellent condition, with no signs of use. It's difficult to find an objective lens of this quality on the used parts market.

It can be used with any microscope from any manufacturer, along with a compatible phase contrast condenser. The microscope must be compatible, meaning it supports RMS objectives, TL = 160 mm, FL = 33 mm.

After installing the 12 mm adapter, this objective lens will have FL = 45 mm.

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.

logo
- knobs operating the internal mechanism
- gear assembly forming the fine focus mechanism (it can be removed because it is a replaceable microscope element)

The entire block fits the Carl Zeiss Jena Lg microscope (from the L-Stativ group), however the fine focus mechanism inside can be unscrewed and as far as I know (to the best of my knowledge) it also fits the microscopes:
- Carl Zeiss Jena Lr
- Carl Zeiss Jena Lu
- Carl Zeiss Jena Lumipan

Description of this part for the microscope.

service replacement part intended for repairing a microscope stage in which this particular component has been damaged. It is not a complete microscope stage.

These rotating stages were used in L-Stativ class microscopes, including:
- Carl Zeiss Jena Lg
- Carl Zeiss Jena Lumipan
- Carl Zeiss Jena Lu
- Carl Zeiss Jena Lr

Please remember that microscopes and microscope parts manufactured by the Soviet company LOMO were often clones of Carl Zeiss Jena products. Therefore, this component may also fit a Lomo microscope stage, but the dimensions should always be compared very carefully before purchasing.

Carl Zeiss Jena manufactured these rotating stages from the 1930s until approximately the end of the 1960s. During that period many small design details were modified, so it is very important to correctly identify the stage model from which this component was removed.

- every photo in the gallery includes a millimetre scale
- the last photos show the microscope stage disassembled, with an arrow indicating exactly where this component is located
- the final photos also show the complete Carl Zeiss Jena Lg microscope fitted with this stage

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

This scale is engraved into a specially shaped brass plate and then silver-plated. After several decades of use, this microscope part often becomes worn and the scale markings may become faint or completely invisible. When restoring such a microscope stage, replacing this scale may therefore be necessary.

Additionally, this microscope part features a locking lever. Once the lever is engaged, the control knob can no longer be turned, locking the upper plate of the microscope stage in the desired position. The operation of this mechanism can be seen in the video available in the video gallery.

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.

Description of this part for the microscope.

Jena microscopes over nearly 100 years. They differ in the appearance of the barrel and in the engraving.

Appearance of this variant of the Carl Zeiss Jena 8x objective:
- black section next to the thread
- silver upper section
- the marking "8/0,20 160/-" on one side of the silver part of the barrel
- the Carl Zeiss Jena logo and the serial number on the other side of the silver barrel

Here (https://www.microscopeparts.eu/part/99852) you will see the same Carl Zeiss Jena 8x objective, but in a slightly older variant (without the value "160/-" engraved on the barrel).

The Carl Zeiss Jena 8x objective is often used for macro photography - both on a microscope and on a camera (with an RMS adapter or a bellows unit). Although it is an achromatic objective, it renders fine detail very well and works nicely for focus stacking. It is a good complement to a set together with the Carl Zeiss Jena Semiplan 3.2x, LOMO 3.7x, Carl Zeiss Jena Semiplan 6.3x and Nikon M Plan 10x objectives.

Basic parameters of this objective:
Manufacturer: Carl Zeiss Jena
Magnification: 8x
Correction: achromatic
Marking on the objective: 8/0,20 160/-
Numerical aperture N.A.: 0.20
Serial number: above 580 000
Tube length: 160 mm
Parfocal length: 33 mm - a so-called short barrel objective
Cover glass: either way - objectives with such a low magnification can work both with and without a cover glass
Immersion: no (a so-called dry objective)
Thread: RMS

Important - this objective is suitable for taking pictures with the "direct-projection" technique, because it does not require plan-compensating optics.

A microscope objective with such a low magnification (keeping the 160 mm tube we get an 8:1 reproduction ratio) is used for observation or macro photography of, among other things:
- insects
- minerals
- inclusions in amber
- handwriting
- micro shells

Why do I describe the appearance of this variant so precisely in the description of this objective? Some users care about completing their Carl Zeiss Jena microscope with parts from the same series and roughly from the same period. The exact way the parameters are written on the barrel makes it possible to compare this objective not only from the photos in the gallery, but also at the level of the text description - especially for AI systems.

This is a so-called "short barrel objective", with a parfocal length of 33 mm. Very often this objective is mounted on a 12 mm extension, which makes it possible to use it in microscopes that require objectives with a parfocal length of 45 mm. Professional adapters with corrective optics work well here, as do plain metal adapters and the popular DIY parts from a 3D printer.

This objective fits practically any microscope from any manufacturer, provided it has an RMS thread and supports objectives with TL=160 mm and a parfocal length of 33 mm (or 37 / 45 mm if we use a suitable adapter). A few examples of such microscopes are listed in the "compatibility" section, but that is not a complete list.

Carl Zeiss Jena objectives are very popular among users of microscopes from other manufacturers. Because of the historical connections, owners of LOMO microscopes treat them as an obvious replacement for their own Soviet optics.

After the Second World War the Carl Zeiss Jena production plant ended up in the Soviet occupation zone, and the Russians began copying the German technical documentation - see for yourself that the LOMO 8x objectives are an exact copy of the objective presented here: https://www.microscopeparts.eu/?search_2=8x&search_7=ob&search_8=lomo. The objectives made for school microscopes such as the Opta Junat are also a clone of Carl Zeiss Jena optics: https://www.microscopeparts.eu/part/00639.
