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.

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.

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

This part may be the answer to the following problems:
- scratched PZO head housing
- how to paint a PZO head?
- how to replace a PZO head cover?
- dropped Biolar head
- dented Biolar PZO head housing

Supported eyepiece diameter: 23.2 mm
- Included: left 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

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.

immersion operation and with a phase contrast ring.

Manufacturer: Lomo
Model: APO-WI-F 70x1,23
Magnification: 70x
Numerical aperture: 1,23
Correction: Apochromat
Tube length: 160 mm
Focal length: 33 mm
Immersion: yes - water
Cover glass: yes - thickness from 0.10 to 0.20 mm
Markings: APO = Apochromat, WI = water immersion, F = phase contrast
Thread: RMS
Year of production: 1972

Note: to work in phase contrast technology you need a Lomo KF-4 condenser (you can see it in the database under number 00653).

This is a professional microscope objective with a very wide range of applications. The main features that make this objective exceptional:
- water immersion is preferred by many users over oil immersion
- very high numerical aperture, allowing the objective to produce a high resolution image
- cover glass thickness correction ring

Standard biological objectives are designed to achieve the best image quality when the specimen is located under a cover glass with a thickness of 0.17 mm (hence the marking on objectives such as 160/0.17). Unfortunately inexpensive cover glasses often do not undergo strict production control and a single package may contain cover glasses with thicknesses of 0.14 mm or 0.19 mm, which reduces observation sharpness.
Thanks to the built-in cover glass thickness correction ring (abbreviated CGTCR, CGCC or CGCR) the objective can be adjusted for every specimen so that it operates optimally. This works even when the actual thickness of the cover glass is unknown, because the effect is simply visible and the adjustment can be done "by eye".

Although this objective is a so-called "short" objective, meaning with a parfocal length of 33 mm, after adding a 12 mm adapter (you can see it in the database under number 99140) it can be used with newer microscopes designed for objectives with a parfocal length of 45 mm.

The Lomo company produced adapters specifically for these objectives (converters) from RMS thread to M27 thread, which makes them a very attractive option for installation in modern Zeiss Axio series microscopes.

Description of this part for the microscope.

compatible with microscopes designed for a 45 mm parfocal standard It is mounted between the objective and the nosepiece/revolver so that optical focus is maintained despite the additional mechanical extension.

Leitz PLEZY differs from extension adapters available on the market in that it features internal anti-reflective optics, ensuring that despite the mechanical extension of the focal length the image quality is not degraded.

monocular (single-eyepiece) PZO MNJ-5 head.

PZO microscope models from the 1950s do not share a common standard for head mounting connectors. However, if the head is not permanently fixed to the microscope, the connector can usually be unscrewed and replaced with another one, allowing the head to be used with microscope models that have a different head mounting interface.

In order to replace the connector in the head, several important conditions must be met:
- the replacement connector must not contain any optical elements
- the replacement connector must have the same thread diameter so that it can be screwed into the head

Basic dimensions:
- internal thread diameter for mounting the connector to the head: 35 mm
- connector diameter at the groove: according to the measurement on the photo, between 31.5 and 32 mm
- connector diameter at the widest point: 34 mm
- diameter of the ring above the connector: 40 mm
- total height of the connector: 35 mm

On the secondary market, it is quite common to find a microscope head with the lower part missing, namely the mounting connector. Why does this happen? Sometimes, when removing the head from the microscope, the user does not realize that it can be pulled out and instead starts unscrewing it. As a result, the head separates from the microscope, but the mounting connector remains in the stand. Such an incomplete head then appears on the secondary market. In this situation, the only way to restore the microscope part to working condition is to add the missing connector element.

This is a service element (repair part) of a PZO MND-5 binocular microscope head. Please note that this is a microscope element (a component) of a microscope part (binocular head) and not a part dedicated to a specific microscope model.

The photos in the gallery show the exact dimensions of the connector described and offered here. In addition, the photos showing the complete head indicate with an arrow which element is being offered and where it is located in the head, so that the part can be clearly identified.

for storing, using, and quickly replacing entire sets of objectives.

For example, you can have separate turrets already equipped with the following sets 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)

Thanks to this , having only one microscope, we can use it for various purposes and not screw in and unscrew all the lenses manually each time.

Monocular microscope head for a fluorescence microscope
Model: PZO MNJ-4
Mounting method: dovetail, diameter 43 mm
Supported eyepieces: 23.2 mm
Mounted filter: OG1 / GG9
For microscopes: PZO Biolar FL and PZO MB-30 FL

Why are monocular microscope heads often used in fluorescence microscopy? Fluorescence microscopy (especially older designs) produces a relatively dark image, so it is beneficial for 100% of the light beam to reach a single eye. A binocular microscope head would split the light 50% to each eye, which could result in an image that is too dark.

The barrier fluorescence filter PZO OG1 / GG9 mounted under the microscope head protects the eyes from the harmful spectrum of fluorescence illumination.

Note - there is also a PZO GG9 fluorescence filter (also available in my catalog). It is important to select the correct filters for the appropriate applications.

The OG1 / GG9 filter is a separate element that can be detached from the microscope head. It is mounted under the microscope head in a dedicated slot provided for this purpose.

Description of this part for the microscope.

maintenance (especially cleaning) of this element is required. Since PZO Biolar microscopes are 40-50 years old, it is now possible to find units without this cover, as it was lost over the years.

This metal cover also acts as a heat sink and dissipates heat from the bulb - this can sometimes be seen as discoloration on the inner surface of the metal. For this reason, replacing it with an element made of cardboard or plastic is a very bad practice.

Without this cover, contaminants can enter the optical light beam, the angled mirror, or the field diaphragm, which may, for example, cause diaphragm failure or deterioration of image quality.

This element fits the following versions of the PZO Biolar microscope:
- B
- B2
- Pol
- DIC
- EPI
- Fluoreszenz

Note - most likely it does not fit the GF version.

This is an original element, taken from the disassembly of a PZO Biolar microscope.

It is an original "from the era" part, coming from a disassembled PZO Biolar microscope.

23.2 mm

Compensating 5x eyepieces are very often used as projection eyepieces for microscope photography.

Description of this part for the microscope.

eyepiece has a worm thread (focus), which allows you to
- sharpen the crosshair image
- or completely remove the crosshair from the image.

The 23.2 mm mounting diameter means this eyepiece can be used with almost any biological / stereo / polarizing microscope - as long as it has a head for eyepieces of this diameter.

6x (and 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, 6x/8x eyepieces provide the best image and optimal magnification.

This part is often damaged in PZO SK8 microscope stages: because the knobs extend beyond the microscope's outline after installation, the worm shaft often bends during transport, making it difficult to straighten properly.

The PZO SK8 is a mechanical microscope stage with horizontal knobs, primarily used in PZO MB30 microscopes, ML series models, and PZO MST-130/131 stereo microscopes - but is also sometimes installed in Studar and Biolar models.

Description of this part for the microscope.

manufactured by PZO and removed from the PZO MB-30 microscope.

Compatible with the following microscopes:
- PZO MB-30 / MB-30S
- PZO ML4 / ML5 / ML6

I need to check if it fits the PZO MS series microscopes.

Description of this part for the microscope.

30S microscope base consists of:
- an illuminator (light source)
- a "tube" containing a collimating lens and a field diaphragm
- a screw securing the tube
- an angle mirror that reflects light at 90 degrees

Two components of this tube are offered here:
- a metal tube with a lens collimating the illumination beam
- a metal tube with a field diaphragm (iris diaphragm)

There are two critical components here: the collimating lens, which often cracks under temperature, and the field diaphragm, whose blades are prone to bending.
