NOTE - Although this is a plan achromatic objective, it does not require dedicated plan compensation optics (e.g., special eyepieces). This makes it very popular for macro photography ? it has a 9:1 magnification ratio, no distortion at the image edge, and operates in direct projection mode.

Description of this part for the microscope.

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 objective is extremely rare on the secondary market and highly professional. Key features:
- Water immersion is preferred by many users over oil immersion
- Very high numerical aperture (1.0) provides high-resolution images
- Use without cover slip allows, for example, direct placement of the objective inside a droplet with the sample to be observed

Despite the "L" marking, the objective can also be used with normal transmitted light illumination.

Lomo objectives marked "L" (luminescence) differ from those without this symbol by:
- Improved UV and blue light transmission
- Lower autofluorescence of the glass
- No or reduced use of organic adhesives in the optical assembly

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.

for all models)

This microscope element consists of two main parts:
- the element that is attached to the microscope stand (in English: microscope stage holder support)
- and the element attached to it in which interchangeable microscope stages are mounted (in English: microscope stage holder). This element contains two screws for centering the microscope stage and a spring-loaded front screw.

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.

It can be used with any microscope from any manufacturer. The microscope must be compatible, meaning it supports RMS objectives, TL = 160 mm, FL = 33 mm.

After installing the 12 mm adapter, this objective lens will have 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.

Manufacturer: Lomo
Magnification: 20x

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.

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.

This model has a metal housing with no lens at its end. Additionally, this housing can be unscrewed without affecting the operation of the objective - resulting in a relatively large working distance of more than 20 mm.

Three features:
- large working distance exceeding 20 mm
- exceptionally high numerical aperture N.A. of 0.15
- achromatic correction allowing direct projection use
make this relatively uncommon model very frequently chosen for macro photography using a microscope objective connected to a camera (focus stacking).

The fact that this objective has FL = 33 mm allows it to be used with microscopes from other manufacturers, including:
- Lomo Biolam
- Lomo MBB-1A
- Carl Zeiss Jena LG / Lu / Lumipan
- Carl Zeiss Jena Nf
- Olympus CH

Note! Please note that the FL = 33 mm focal length means that this objective DOES NOT FIT the following microscopes:
- PZO Biolar
- PZO Studar

Early versions of this objective (with low serial numbers) have the engraved marking 5/0.15 160/0 suggesting that the objective is intended for use without a cover glass. This is true, but more precisely this objective can work both without a cover glass and with one. In newer versions the engraving already reads 5/0.15 160/- where this "minus" already means "indifferent".

Specimen protection: yes, the objective has a spring-loaded front mount that prevents breaking the slide with the specimen
Thread: RMS

Why do I state the year of manufacture in the description of this objective? Older LOMO microscope parts (objectives, microscopes, heads) have the year of manufacture encoded in the serial number: the first two digits of the serial number are the year of manufacture. Many users want to complete their microscope with parts made in the same year as the microscope itself.

This is a so-called short barrel objective with a parfocal length of 33 mm. Very often this objective is mounted on a 12 mm extension, which allows it to be used in microscopes that require objectives with a 45 mm parfocal length. Professional adapters with protective optics, metal adapters and popular DIY 3D-printed adapters all work well here.

Fun fact: LOMO manufactured adapters from the RMS thread to M27. Thanks to them, this objective was used on LOMO Biolam I and LOMO Biolam M microscopes. Users of Carl Zeiss Axio series microscopes with the M27 thread took advantage of this as well and used these adapters too.

LOMO objectives are very popular among users of microscopes from other manufacturers. Because of the historical ties, owners of Carl Zeiss Jena microscopes regard them as a natural replacement for the German objectives.

This objective fits practically any microscope of any manufacturer, as long as it has an RMS thread and takes objectives with a 160 mm tube length and a 33 mm parfocal length (or 37 / 45 mm with a suitable adapter). Several example microscopes are listed in the "Compatibility" section, but this is not a complete list.

Year of manufacture: 1966
Tube length: 160 mm
Parfocal length: 33 mm - so-called short barrel objective
Cover glass: not critical - objectives with such low magnification work both with and without a cover glass
Immersion: no (dry objective)
Thread: RMS

The LOMO 8x objective (model 8 0.20) is frequently used for macro photography with a microscope or a camera (via an RMS adapter or a bellows). Although it is an achromat, it renders fine detail very sharply and performs well in focus stacking. It complements a set together with the LOMO 3.7x, Carl Zeiss Jena Semiplan 6.3x and Nikon M Plan 10x.

Important - this objective is suitable for direct projection photography, as it does not require plan-compensating optics.

A microscope objective with such low magnification (with a 160 mm tube length it gives an 8:1 reproduction ratio) is used, among other things, for observing or photographing:
- insects
- minerals
- inclusions in amber
- handwriting
- micro shells (micromollusks)
- and much more

Why do I state the year of manufacture in the description of this objective? Older LOMO microscope parts (objectives, microscopes, heads) have the year of manufacture encoded in the serial number: the first two digits of the serial number are the year. Many users want to complete their microscope with parts made in the same year as the microscope itself.

This is a so-called short barrel objective with a parfocal length of 33 mm. It is very often mounted on a 12 mm extension, which allows it to be used in microscopes that require objectives with a 45 mm parfocal length. Professional adapters with protective optics, metal adapters and popular DIY 3D-printed adapters all work well here.

Fun fact: LOMO made adapters between the RMS and M27 threads. Thanks to them, this objective was fitted to the Lomo Biolam I and Lomo Biolam M microscopes. Owners of Carl Zeiss Axio series microscopes with M27 thread also took advantage of this and used these adapters.

LOMO objectives are very popular with owners of microscopes from other manufacturers. Due to historical ties, owners of Carl Zeiss Jena microscopes regard them as an obvious replacement for the German objectives.

This objective fits practically any microscope from any manufacturer, as long as it has an RMS thread and accepts objectives with TL = 160 mm and 33 mm parfocal length (or 37 / 45 mm with a suitable adapter). Several example microscopes are listed in the "compatibility" section, but the list is not complete.
