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 not 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.

These are the exact components marked with numbers 3 and 5 in the instruction manual sketch.

Inside there is a classic mirror reflecting light and a matte mirror diffusing light. Both are in very good condition.

Note - this base does not fit the first models of Carl Zeiss Jena Technival and Citoval stereomicroscopes, as they have a smaller stand foot.

The complete factory set consists of:
- transmitted light base
- wrist supports
- light source
Here I present and offer only the base - without wrist supports and without the light source.

- PZO KPI-2 (Pluta / Nomarski DIC)
- PZO K4Ph (phase contrast Ph, PhA, PhS, A)
- PZO K3Ph (phase contrast Ph, PhA, PhS, A)
- PZO K3Ph1 (phase contrast Ph, PhA, PhS, A)
- PZO KFL (phase contrast / darkfield for fluorescence)
- PZO KFF
- PZO K3Phz (variable phase contrast Phz)

This upper lens allows conversion of the mounting standard from PZO 39.5 mm to the 37 mm standard and the use of PZO condensers on many other microscopes, e.g. Olympus BH / CH-2 or Lomo MBB

This microscope element can solve the following issues:
- How to mount PZO DIC on a Lomo microscope?
- Can I install a PZO DIC KPI2 condenser on an Olympus CH-2 microscope?
- Can I use PZO phase contrast on my non-PZO microscope?
- Does PZO phase contrast or DIC work on a microscope with a 37 mm condenser mount?

correction of vision defect in one eye and proper image focus adjustment.

Basic parameters:
- Type: tube with diopter correction ring
- Supported eyepiece diameter: 23.2 mm
- Maximum length: 45 mm
- Color: steel

Steindorff Berlin produced two main types of binocular microscope heads:
- with straight tubes
- with diverging tubes in the "Y" standard.
In each of them, eyepiece tubes with a length (maximum length measured with the diopter adjustment ring fully unscrewed): 45 mm or 50 mm could be installed.

I was not able to find information what this depended on:
- maybe some tubes were older and others newer
- maybe some were designed for TL=170 mm and others for TL=160 mm
- maybe some matched objectives FL=37 mm and others FL=45 mm

This element may answer the following issues related to the Steindorff Berlin microscope:
- Is it possible to have diopter adjustment on both eyepieces?
- How to straighten a bent eyepiece tube?
- Diopter adjustment does not work - how to replace the grease?

micrometer scale: no
- dedicated for polarization: no
- material: brass
- 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.

have an interchangeable objective turret.

This is an excellent solution for owning, 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.

This is the newest, matte version of the objective revolver. If you're looking for the glossy version, see here: https://www.microscopeparts.eu/00736.

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

03
Magnification: 32x
Correction: achromat
Numerical aperture: 0.4
Tube length: 160 mm
Focal length: 45 mm
Cover glass: yes, 1 mm (!)
Immersion: no
Thread: RMS
Ph1: phase contrast
LD: "long distance" meaning long working distance

Note: this is an objective for an inverted microscope, therefore it is corrected for observation through a 1.0 mm cover glass

It can be used with any inverted microscope from any manufacturer together with a compatible phase contrast condenser (or slider with phase rings). Of course the microscope must be compatible, i.e. support RMS objectives, TL=160 mm, FL=45 mm.

It can very likely also be used with other inverted Zeiss microscopes (e.g. Axiovert 25).

Tube length: 160 mm
Focal length: 45 mm
Cover glass: indifferent
Immersion: no
Thread: RMS
Ph1: phase contrast

This specific unit was used in an inverted Zeiss ID 02 microscope, but I have also seen this objective model in Zeiss KF-2 ICS and Zeiss Axiostar microscopes.

Objectives with such low magnification (here 10x) can be used without a cover glass, with a cover glass, or for observation through thicker glass (e.g. through a Petri dish), therefore they can be used both in upright and inverted microscopes.

It can be used with any microscope from any manufacturer together with a compatible phase contrast condenser (or slider with phase rings). Of course the microscope must be compatible, i.e. support RMS objectives, TL=160 mm, FL=45 mm.

10x
Correction: Achromat
Numerical aperture: 0.24
Tube length: 160 mm
Focal length: 45 mm
Cover glass: no
Immersion: no
Thread: RMS
Info: PI = polarization-interference objective (red ring).

Compatible with the following PZO condensers:
- PZO KPI 2
- slit condenser
PI objectives are among the components of the PZO UPI set (i.e. the so-called DIC).

VERY IMPORTANT: the marking on the objective is "PI" (in lowercase: "pi"), meaning [P]-polarization [I]-interference.
In many descriptions available on the Internet, you can find information that this is a PLAN objective. This is an ERROR caused by misinterpreting the marking as PL.

Note: another INCORRECT piece of information often found online is that these are DIC objectives. This is not true.
DIC according to Pluta (niem: DIC nach Pluta), sold by PZO, achieves the DIC effect (i.e. a 3D relief image) using standard achromatic PZO objectives (and not only those). Objectives marked PI with a red ring are not required for this.

It can be used with any microscope from any manufacturer that supports RMS objectives, TL=160 mm, FL=45 mm.

Mounting diameter: 39.5 mm
Iris diaphragm: yes
Filter holder: yes, for round filters with 32 mm diameter
Removable top lens: yes

This is a very rarely encountered condenser designed for use with high numerical aperture objectives (e.g. Nikon Plan Apo or Leitz PL-Fluotar Oel Fluoreszenz).

This condenser fits microscopes from many manufacturers (e.g. PZO, Zeiss, Carl Zeiss Jena, Leitz, Kremp Wetzlar, Will Wetzlar and many others) with a condenser holder diameter of 39.5 mm.

- missing eyepiece tube in the microscope
- eyepiece cannot be inserted into the tube
- eyepiece tube in the microscope is deformed

In the last photos, an arrow shows where this element is located inside the microscope head, allowing precise identification.

Description of this part for the microscope.

it is the left metal holder for the eyepiece prism
- at the same time it is the mounting thread into which the eyepiece tube is screwed

Important: this is the LEFT prism holder. In the head of the Zeiss DRC microscope (and other Stemi D series models) there are two such holders - left and right - and they are not identical.

This element is made of an alloy that very often breaks (this can be seen in one of the last photos in the gallery).

Fits the following models:
- Zeiss D
- Zeiss DR
- Zeiss DRC
- Zeiss DV-4

This microscope part may solve the following problems occurring in a Zeiss Stemi D, DR, DRC or DV 4 microscope:
