Description of this part for the microscope.

ring that allows correction of the vision defect of one eye and proper adjustment of image sharpness. The right eyepiece prism is integrated together with the tube.

Basic parameters:
- Type: tube with diopter correction ring
- Supported eyepiece diameter: 23.2 mm
- Included: right eyepiece prism
- For head model: PZO MND-6, both for models with black and with white housing.

This repair part (service element / replacement part) comes from a binocular head PZO MND-6 which was originally mounted on the microscopes:
- PZO Biolar DIC
- PZO Biolar B

However, because the PZO MND-6 head has a standard mounting interface typical for PZO microscopes (that is a dovetail mount with a diameter of 43 mm), this head can also be found mounted on other PZO microscopes such as:
- Studar
- MB-30

Additional information: the fluorescence microscope PZO Biolar FL was originally sold with a mono head (monocular head) - however the PZO MND6 head also fits this microscope model.

Hinweis - this tube with prism DOES NOT FIT heads that were originally sold with PZO Studar microscopes, even though these heads look very similar. Of course if a head from the Biolar model was mounted on a Studar microscope (because it fits), then this tube will be compatible, because it is a repair element for the HEAD and not for a specific microscope model.

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?

08 160/-
Color correction: Planachromat
Numerical aperture: 0.08
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

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.

New (usually Chinese) microscope filters are sometimes not even made of glass. And even if they are made of glass - you may encounter scandalous examples where the glass is only surface-colored. Unfortunately, cheap colored glass filters may not be internally homogeneous and can cause light refraction distortions.

This filter set by PZO was originally sold together with the PZO Biolar microscope. It was manufactured in the 1970s (and certainly before 1977), so these are optical glasses that are about half a century old! They have never been used until now (this is so-called NOS - New Old Stock), therefore these are excellent old-class optical glasses of the highest quality.

Filters with a 32 mm diameter are used - and can be used - in microscopes from various manufacturers:
- Carl Zeiss Jena
- Zeiss West Germany
- Eschenbach
- Meopta
- Nikon
- ROW
- Leitz Wetzlar
- Wild
- Hund
- Kosmos
- and many others

Important - popular microscopes by Lomo (for example Lomo Biolam) have a 33 mm filter holder, so the filters shown here have too small a diameter and may fall out from some Lomo holders.

PZO Biolar P (Pol)
- PZO Biolar FL (Fluorescence)

The function of this component is to reflect light coming from the microscope base vertically upward so that, after passing through the specimen slide and the objective, it reaches the eyepieces and ultimately the user's eyes.

This cast component bears the marking "AK11", and this designation is commonly used on the secondary market to identify this particular angle mirror. However, it is not a part number, because the marking "AK11" can also be found on other PZO microscope components, which may lead to confusion. It is very likely that the source of this confusion is the attempt to compare PZO metal components with those used in Carl Zeiss Jena microscopes, where cast parts are marked with numbers in the format "Si10 CZ xxxxx". This may incorrectly lead people to assume that PZO used a similar numbering system.

Replacement of the angle mirror in PZO Biolar microscopes may be necessary in the following situations:
- if the mirror has become heavily scratched due to improper cleaning (minor scratches are usually not visible during normal use)
- if the silver reflective coating of the installed mirror becomes oxidized
- if the mirror becomes damaged, chipped, or cracked, for example after coming loose from its mounting

intended for so-called "thick" objectives
Thread in the cap: no, the cap of this objective case does not contain a thread for attaching an RMS objective

This objective case can be used to store so-called "short" objectives (DIN 33 mm), longer objectives (DIN 37 mm), and long objectives (DIN 45 mm), provided they are not the so-called "thick" type.

For PZO objectives, it can accommodate all standard achromatic objectives as well as all phase contrast objectives. Some unusual PZO microscope objectives do not fit inside, for example the 100x PI objective (with a red ring).

Various names are used on the secondary market for a microscope objective case, including:
- objective case
- microscope objective case
- objective container
- microscope objective container
- objective storage case
- objective storage container
- objective box
- objective storage box
- protective objective case
- objective lens case
- objective lens container
- dust protection case
- transport case for microscope objectives
- microscope objective holder case
- storage canister for microscope objectives

Each case has the PZO logo on its cap. Caps may be black, white, or grey.

Although this case is of greatest interest to users and collectors of objectives made by the Polish manufacturer PZO, it can of course be used to store objectives from any manufacturer.

This tube makes it possible to connect a camera or photographic camera to a trinocular head or directly to the microscope body, even when no trinocular head is installed.

Originally, this adapter was designed for the Lomo TRN-1 trinocular head. This head was used in Lomo Polam polarizing microscopes from the early 1970s onwards.

Several remarks regarding the model designation of the trinocular head for which this component was originally intended:
- the name Lomo TRN-1 is the Latin alphabet designation. In Cyrillic script the model designation appears as TPH (for example model TPH1Y4.2), and this designation is used in the manual for the Lomo Polam L-211 microscope
- the vast majority of these trinocular heads are not marked with any model designation
- the Envirotools website http://www.envirotools.hu/ateso_fenyu_polarizacios_mikroszkop.htm refers to this trinocular head as HU-POL

In the last photograph, an arrow indicates exactly which component is being offered and where it is located in the Lomo Polam microscope, allowing this part to be identified unambiguously.

Basic technical parameters of this tube:
Mounting method to the trinocular head or microscope: 41 mm dovetail mount (this is also the Carl Zeiss Jena standard)
Camera mounting method: male M39 thread
Alternative camera mounting method: since the M39 thread can be removed, a plain smooth tube with a diameter of 35 mm remains
Additional optics: yes, the original optics are installed inside, although they can be removed, leaving only an "empty tube".

This is not "a tube dedicated to a specific microscope model". It is a tube originally mounted on the third port (photo port) of a trinocular head. Since a trinocular head can be installed on microscopes other than the model with which it was originally supplied, this tube can be regarded as a universal accessory.

These technical parameters make it possible to use this tube with virtually any microscope manufactured by:
- Lomo (for example Biolam, Polam, MBB-1A and others)
- Carl Zeiss Jena (for example Ergaval, Amplival, Jenamed and others)
- IOR, Meopta and other manufacturers using a 41 / 41.5 mm dovetail mount

In addition, a 41 mm dovetail tube can easily be mounted on microscopes equipped with a 42 mm or 43 mm opening, for example:
- Olympus (for example CH, CH-2, BH-2 models)
- PZO (for example Biolar, Studar, MB-30 and others)

The entire list of microscope manufacturers and models given above may also be treated as a list of microscopes compatible with the Lomo TRN-1 trinocular head. Indeed, many examples can be found on the Internet showing this head being used with microscopes made by manufacturers other than Lomo.

Because this tube is equipped with an M39 thread by default, almost any camera or photographic camera can be attached by means of a suitable adapter, for example:
- devices with M42 threads
- devices with C-mount threads
- Nikon, Sony, Olympus and other camera standards

This is therefore a universal photo tube featuring a 41 mm dovetail on one side and either an M39 thread or a 35 mm tube on the other side.

In the image gallery, every photograph includes a millimetre scale, and in addition, the dimensions of the dovetail, tube and thread have been measured with calipers so that compatibility can be determined precisely.

Wetzlar
Model: 160/0,17 EF 100/1.25 OEL PHACO 3
Magnification: 100x
Correction: semi-plan achromat
Numerical aperture: 1.25
Tube length: 160 mm
Focal length: 45 mm
Cover glass: yes, 0.17 mm
Immersion: yes, oil
Thread: RMS
Specimen protection: yes - spring-loaded
Info: PHACO 3 = phase contrast

Some important information about this objective:
- the designation "EF" means "Extended Field" - this is a semi-plan achromatic objective with an 18 mm field of view, which should be taken into account when selecting suitable eyepieces
- the semi-plan achromatic correction is "almost flat" - it is no longer an achromat, but not yet a plan achromat
- this objective can be used in brightfield, but phase contrast operation requires a compatible phase contrast condenser or a slide (slider) with a phase ring diaphragm
- the designation PHACO 3 means that for phase contrast operation a phase contrast condenser set to ring "3" should be used (the equivalent setting used by Zeiss is called "Ph3")
- this objective can be used with microscopes designed for objectives with a 170 mm tube length, but in such a case the optical path must be extended by 10 mm - most commonly by pulling the eyepieces out of the tubes by 10 mm

This objective can be used with any microscope from any manufacturer together with a compatible phase contrast condenser. Naturally, the microscope must be compatible, i.e. it must support RMS objectives, TL=160 mm and FL=45 mm - or have adapters that make such adaptation possible (for example thread adapters).

and serve two main purposes:
- they allow the user to comfortably rest their head against the eyepieces, reducing neck strain during prolonged microscope work (this is not possible with soft rubber eyecups)
- they block stray light entering from the sides, reducing reflections and improving image contrast

This offer includes 2 (two) pieces, i.e. one pair.

A few quick facts:
- these eyecups fit PZO eyepieces only
- these eyecups fit only PZO eyepieces with a mounting diameter of 23.2 mm
- these eyecups DO NOT FIT older PZO eyepieces with a knurled outer edge — an example of such eyepieces can be seen in the last gallery photograph
- the last gallery photograph shows an example of these eyecups installed on microscope eyepieces

Important: no dimensions are provided here. These eyecups fit only 23.2 mm microscope eyepieces manufactured by PZO (PZO Poland / PZO Warszawa). They do not fit microscope eyepieces made by other manufacturers. If a microscope made by another manufacturer (e.g. Lomo Biolam) uses PZO eyepieces, these eyecups will fit. If a PZO microscope (e.g. PZO Biolar) uses eyepieces made by another manufacturer (e.g. Carl Zeiss Jena), these eyecups will not fit even though the microscope itself is made by PZO. These eyecups fit the eyepieces — not a specific microscope.

ameters:
Manufacturer: Lomo
Model: PLAN 25x0.50 P
Original designation: ЛОМО ПЛАН 25х0,50 П
Magnification: 25x
Numerical aperture N.A.: 0.50
Tube length: 160 mm
Cover glass: yes, 0.17 mm thickness
Immersion oil: no – this is a dry objective
Focal length: 45 mm
Thread type: RMS
Additional designation: P (Cyrillic: П) indicates that this objective is designed for use with polarized light
Special features: built-in iris diaphragm
Year of manufacture: 1976

This objective has a standard RMS thread and TL=160 mm, which means it can be used with the vast majority of microscopes from virtually any manufacturer, including Olympus, Zeiss, Nikon, PZO, Carl Zeiss Jena, Reichert, Wild and many others.

The built-in iris diaphragm allows, among other things, precise centering of the objective, because in a polarizing microscope the following diaphragms may operate simultaneously:
- field diaphragm in the illuminator
- aperture diaphragm (or two aperture diaphragms) in the condenser
- iris diaphragm in the microscope objective
- iris diaphragm in the eyepiece head
and accurate centering of all of them relative to each other is very important in polarized-light observations.

Objectives marked "P" / "Pol" feature a special construction in which the lenses are mounted and cemented in a way that prevents mechanical stress. They can be used both for conventional brightfield microscopy and for observations in polarized light.

The nameplate fits all microscopes of the Biolar series based on the PZO Biolar B stand:
- PZO Biolar B
- PZO Biolar DIC
- PZO Biolar FL
- PZO Biolar Pol
- and all other variants
All of these nameplates are identical and differ only by the serial number.

Important: this nameplate does NOT fit the microscopes currently (as of 2026) sold as the Biolar C. These are ordinary Chinese OEM microscopes with a "Biolar" sticker.

Several decades have passed since the PZO Biolar series microscopes were manufactured, and these nameplates often simply fall off by themselves.
