Description of this part for the microscope.

Model: Lomo INF
Mount diameter: 35 mm

This insert fits condensers used in the following Lomo microscopes:
- MIK-1
- MIK-4
- Polam (all models)
- MIN-8

and most likely also in other microscopes that use similarly designed condensers. Note - to make sure that this insert fits your condenser, be sure to check the diameter of this element.

The transmitted light condenser in these microscopes features:
- interchangeable upper lenses to obtain the required aperture
- a diaphragm located below the upper lens
- a slot for inserting a IR filter insert (the insert may, but does not have to, include an additional iris diaphragm)

In some cases, this insert alone can be used without the condenser - the effect is similar to a condenser with a IR filter of low N.A.
This element is often used by owners of microscopes from other manufacturers to convert their condenser into a infrared condenser.

Since this element can be removed relatively easily, it is very often missing in microscopes from the secondary market.

IMPORTANT - this is not a separate microscope condenser. It is a component of the condenser, even though it is sometimes used as a substitute for a condenser.

Description of this part for the microscope.

differences between the Lomo MIN-8 and MBB-1A microscopes is the position of the light beam collimating lens:
- in the Lomo MBB-1A microscope this lens is normally located below the Abbe condenser
- in the Lomo MIN-8 microscope this lens is located in the base, in the light path directly behind the field diaphragm

Here I present and offer the complete mechanism for mounting and moving this lens:
- lens in housing
- rod on which the lens is mounted
- holder allowing movement of the lens
- mounting screws

This lens is used to shape the light beam so that the specimen is evenly illuminated at low magnifications.

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.

Description of this part for the microscope.

Manufacturer: Carl Zeiss
Name: POL analyzer for simple polarization
Intended for: monocular biological microscopes
Type: for use with transmitted or reflected light

Hinweis: Please check whether the eyepiece diameter is suitable in order to mount the analyzer onto it. The dimensions of the analyzer housing are visible in the photos, and the housing also has a certain tolerance range.

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.

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.

length: (?)
Cover slip: no
Thread: RMS + Pol adapter

This objective is for use with transmitted or reflected light.

This specific item was used with the Lomo MOIN-6 microscope.

The RMS-thread objective is mounted on a suitable sleeve that allows using the objective in Lomo MPD-1 / Lomo MIN-6 / Lomo MIN-8 / Lomo MIN-1 / Lomo Polam microscopes. Of course, the objective can be unscrewed and another objective can be screwed into the sleeve.

The Pol adapter also allows centering the objective relative to the entire optical path - this requires tools (wrenches / tools).

Info: I have repeatedly seen information stating that this RMS-Pol adapter is compatible with Leitz Wetzlar polarization microscopes - but I have not personally checked this.

- 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.

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 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

Info: PI = polarization-interference objective (red ring).

Compatible with the following PZO condensers:

- 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.

Description of this part for the microscope.

On the condenser, the model name is written in Cyrillic and looks similar to ON-14.

The Lomo OI-14 condenser has a removable (unscrewable) top lens:
- A1.4 with high aperture, for use with objectives with high numerical aperture (which corresponds to high magnifications, it can be assumed above 40x)
- A0.3 with low aperture, for use with low magnification objectives

Although it is possible to work with low magnification objectives (e.g. 5x or 10x) using a condenser with the A1.4 lens installed - the image is too "sharp" and contrasty. In this case, replacing the lens with A0.3 allows obtaining a pastel, soft and visually pleasant image.

Since the Lomo OI-14 condenser has been produced since the 1960s, over the years this additional lens has very often been lost and most condensers available on the secondary market have only one - most often A1.4.

The Lomo OI-14 condenser has a mounting diameter of 37 mm, but since it is very popular among microscope users, an extension ring is often used, allowing it to be mounted in microscopes with a 39.5 mm condenser holder. This condenser fits microscopes from various manufacturers: Lomo, PZO, Zeiss, Carl Zeiss Jena, Meopta, IOR, Olympus, ROW, Nikon, Leitz Wetzlar and many others.

Numerical aperture: 0.40
Tube length: 160 mm
Focal length: 33 mm
Cover glass: yes, 0.17 mm
Thread: RMS + Pol adapter
Info: P = Polarization

This is an objective designed for transmitted light work with a cover glass.

The RMS thread objective is mounted on a dedicated slide-in adapter that allows it to be used in Lomo MIN series and Lomo Polam series microscopes. Of course, the objective can be unscrewed and another objective can be mounted in the adapter.

The objective itself, once removed from the adapter, is a standard objective that can be used in virtually any microscope with an RMS thread. It is a so-called "short objective" (focal length 33 mm). When a 12 mm adapter is added, the total length becomes 45 mm, allowing it to be used with newer microscopes from any manufacturer.

Lomo polarization objectives with RMS thread can be installed in an RMS-M27 adapter and then used in microscopes such as Lomo Biolam M, Lomo Biolam I, Lomo Lumam, or Lomo ML-2. I have also frequently seen such objectives used in Zeiss Axio series microscopes with M27 thread.

The Pol adapter also allows precise centering of the objective relative to the entire optical path - this requires tools (keys / tools).

Info: I have repeatedly seen information stating that this RMS-Pol adapter is compatible with Leitz Wetzlar polarization microscopes - however, I have not personally verified this.

In summary, this objective is dedicated to Lomo MIN-1, MIN-4, MIN-5, MIN-6, MIN-8, Lomo Polam R-113, Polam L-211, Polam L-213, Polam R-311, Polam LMPR microscopes - but it is practically compatible with any microscope from any manufacturer that supports 160 mm objectives.

Description of this part for the microscope.

Note - this model of microscope objective is very often used for macro photography and focus stacking. More information on this can be found at the end of this description.

Manufacturer: Lomo
Magnification: 9x
Model: PLANACHR 9x0.20 P
Numerical aperture: 0.20
Optical correction: planachromatic (flat field)
Tube length: 160 mm
Focal length: 33 mm
Cover glass: optional, can be used but is not required
Thread: RMS + Pol adapter
Info: P = Polarization

The RMS thread objective is mounted on a dedicated slide-in adapter that allows it to be used in Lomo MIN series and Lomo Polam series microscopes. Of course, the objective can be unscrewed and another objective can be mounted into the adapter.

The objective itself, once removed from the adapter, is a standard objective that can be used in virtually any microscope with an RMS thread. It is a so-called "short objective" (focal length 33 mm). When a 12 mm adapter is added, the total length becomes 45 mm, allowing it to be used with newer microscopes from any manufacturer.

Lomo polarization objectives with RMS thread can be installed in an RMS-M27 adapter and then used in microscopes such as Lomo Biolam M, Lomo Biolam I, Lomo Lumam, or Lomo ML-2. I have also frequently seen such objectives used in Zeiss Axio series microscopes with M27 thread.

The Pol adapter also allows precise centering of the objective relative to the entire optical path - this requires tools (keys / tools).

Additionally, this objective is very often used for macro photography even without a microscope. This objective does not require a cover glass and works in the "direct-projection" technique, meaning it can be connected directly to a camera without additional optics. This allows achieving a very high magnification scale and great depth of field across the entire image when using focus stacking. The fact that this is a polarization objective (i.e. stress-free optics without internal glass tensions) further improves image quality at high magnifications.

Description of this part for the microscope.

condenser fits microscopes from many manufacturers (e.g. Lomo, Carl Zeiss Jena, Olympus and many others) with a condenser holder diameter of 37 mm.

Description of this part for the microscope.

for taking microscope photographs or recording microscope videos. This is a gray photographic adapter.

Basic technical parameters:
- mounting connection to microscope stand: 41 mm dovetail
- output connection type on the photo port: 49 mm internal thread
- connection for binocular head mounting: Jena standard 41 mm dovetail
- magnification directed to the binocular head: 1.6x
- magnification on the photo output: none (that is 1.0x)

Because this photo head has a 49 mm threaded output, virtually any device, camera, adapter, tube or other accessory can be connected after using an appropriate 49 mm thread adapter. Direct projection technique may be used (because there is no additional optics inside), or any projection eyepieces may be installed in the optical path.

This photographic attachment is intended mainly (but not exclusively) for the following microscope models:
- Carl Zeiss Jena Eduval
- Carl Zeiss Jena Laboval
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival
- Carl Zeiss Jena Vertival
- Carl Zeiss Jena Epival
- Carl Zeiss Jena Metaval
- Carl Zeiss Jena Telaval
- Carl Zeiss Jena Pictoval
- Carl Zeiss Jena Epignost

The list above contains Mikroval series microscopes with gray housings - just like the tube shown and offered here. However, it also works with older black Carl Zeiss Jena microscopes:
- Carl Zeiss Jena L-Stativ (models Lg, Lu and Lr)
- Carl Zeiss Jena Lumipan
- Carl Zeiss Jena Ng
- Carl Zeiss Jena Nf (and NfPk)

Please note that microscopes from other manufacturers also use the 41 / 41.5 mm dovetail connection standard. Because of this, this photographic head can also be used with microscopes made by:
- Lomo (for example Lomo Biolam)
- Meopta
- IOR
- selected Reichert microscopes (for example Reichert Neozet)
- Will Wetzlar
- Hund Wetzlar
- Leitz Wetzlar

This Carl Zeiss Jena tube is also very often used with microscopes having a larger head mounting diameter. In such cases users apply additional spacer or thickening rings. Because of this, this photo adapter also fits microscopes from manufacturers such as:
- PZO (for example the PZO Biolar model with 43 mm connection)
- Olympus (for example the Olympus CH model with 42 mm connection)

The element that allows a photographic camera or imaging camera to be connected to Carl Zeiss Jena Mikroval series microscopes may be referred to by different names. Commonly used names include:
- trino head
- trinocular head
- photo head
- photographic head
- photo attachment
- photographic attachment
- photo adapter
- photographic adapter
- photo tube
- photographic tube
- phototube
- photographic angle tube
- and various combinations of the words head, attachment, adapter or tube with terms such as photo, photographic, for camera and similar
