This set is often used with Carl Zeiss Jena microscopes. To use it with microscopes from dozens of other brands, a condenser adapter is used, changing the condenser mounting diameter to 39.5 mm, and adapters changing the focal length of the objectives to 45 mm. It can then be used with PZO, Olympus, Nikon, Hund Wetzlar, Will Wetzlar, and most other microscopes with a TL of 160 mm.

Lomo OI-35 Koehler illuminator with field diaphragm
- illuminator plug with Lomo 8V 20W BA15d bulb

Fits microscopes including:
- Lomo Biolam
- Lomo Biolam M
- and certainly many other models (e.g., Polam)

A small, non-Koehler illuminator for these microscopes is the Lomo OI-21, which is mounted on a base like the OI-35 (and therefore does not use a mirror). The Lomo OI-19 is an external illuminator that shines onto the mirror. The Lomo OI-35 uses the same filament bulb as these two, but now allows for Koehler standard lighting.

Koehler standard lighting allows for the best image quality when working with oil immersion or phase contrast.

The last photos are an example of use.

Mounting: 41 mm dovetail (Carl Zeiss Jena standard)

The head features adjustable interpupillary distance and diopter adjustment for one eyepiece.

This export version was sold in Western Europe, primarily under the Bresser brand. Biolam microscopes were sold under this name (thus as Bresser Biolam). NOTE - a small batch of these microscopes was sold under the Bresser Erudit name - but the "Erudit" is now a completely different Bresser microscope.

This is an exact clone of the Carl Zeiss Jena microscope head and is therefore very commonly used for these microscopes.

Note: The 1.5x magnification head requires a relatively large amount of light. Furthermore, the optimal image is obtained with 7x or 8x eyepieces (the maximum is 10x). Higher eyepiece magnification results in "empty magnification" and the image may not be sharp.

- 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.

1 microscopes have simple microscope stages with grips for holding the specimen. Therefore, at magnifications above 400x, manually manipulating the slide with the specimen becomes very difficult. XY cross stages are used for this purpose, for example, to move the specimen very precisely at 900x magnification with oil immersion.

This is not a cheap plastic cross stage - it is a well-made Lomo design, very popular on the used microscope market.

NOTE - if the mounting pin spacing matches, this cross stage can be mounted on stages from virtually any manufacturer.

This is an objective for working with reflected light (but also transmitted light) without a cover slip.

Objective with RMS thread, but can be screwed into an adapter for M27 thread, allowing use in a microscope, e.g., Biolam-M. Of course, the objective can be unscrewed and another objective can be screwed into the adapter.

Info: M27 thread is also a standard used by Zeiss Axio microscopes. Therefore:
- this objective can be used in Axio microscopes with M27 thread
- this adapter can be used in Axio microscopes with another objective

This adapter is not a 3D-printed plastic part - it is a professional, metal, original product by Lomo.

- Numerical aperture: 1.0
- Design: condenser with a double-lens optical system
- Mounting diameter: 37 mm (exactly according to the manufacturer catalog 36.8 mm)
- Iris diaphragm: YES

Note - although the manufacturer describes it as "for polarizing microscopes" - this is NOT a polarizing condenser, i.e. it does not contain a polarizer - neither fixed nor rotatable.

This condenser fits any Meopta microscope as well as microscopes from other manufacturers (e.g. Lomo, Olympus, Carl Zeiss Jena and many others) with a condenser holder diameter of 37 mm.

where the letter "H" corresponds to the Latin "N". This means that the model name written in the Latin alphabet is KON-3, where "KON" is simply an abbreviation of the word condenser.

Basic data:
- Element: Abbe microscope condenser
- Manufacturer: Lomo
- Manufacturer designation: KOH-3
- Numerical aperture: 1.2
- Numerical aperture with top lens removed: 0.3
- Mounting diameter: 37 mm
- Iris diaphragm: YES
- Wide-field lens: YES, with the possibility of moving it into / out of the light path
- filter holder: YES

This condenser also fits microscopes from other manufacturers (e.g. Meopta, Olympus, Carl Zeiss Jena and many others) with a 37 mm condenser mount.

Important: Although the mounting diameter of the KOH-3 condenser is 37 mm, the top lens slightly protrudes beyond the condenser body. For this reason, in some cases installation requires the following steps:
- unscrew the top lens
- install the condenser in the holder
- screw the top lens back in

Note: If you use this condenser with a microscope from a manufacturer other than Lomo, please note that:
- the filter holder is designed for filters with a diameter of 33 mm
- while most manufacturers use the 32 mm standard diameter
As a result, 32 mm filters cannot be used in the KOH-3 condenser without modification - they simply fall out because the holder diameter is too large.

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 focal 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 focal 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.

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 right clamp, which does have a spring.

Fits condensers:
- 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?

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.

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
