Description of this part for the microscope.

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.

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.

microscope from any manufacturer that allows the use of eyepieces with a mounting diameter of 23.2 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
Model: 20 0.40 P
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.

- Model: 5/0.15 160/-
- Alternative model marking: 5/0.15 160/0
- Magnification: 5x
- Numerical aperture N.A.: 0.15
- Correction: achromatic
- Focal length FL: 33 mm
- Tube length: 160 mm
- Cover glass: not required, but may be used
- Immersion: no (dry objective)
- Thread: RMS

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".

Because this is important, I will write it again: this is a single eyepiece, not a pair of eyepieces.

This is a solution for people who:
- either have a pair of these eyepieces, but one of them needs to be replaced
- or have a microscope with a monocular head

For Will Wetzlar microscopes, eyepieces from practically any manufacturer can be used, provided that they are designed for a finite tube length system and have a mounting diameter of 23.2 mm. However, many users appreciate having original parts.

This eyepiece also works the other way around - it fits almost any microscope from any manufacturer that allows the use of eyepieces with a mounting diameter of 23.2 mm. Users of microscopes from many manufacturers are happy to choose German eyepieces because of their high quality. I have included some examples in the "compatibility" section, but this is definitely not a complete list.

Numerical aperture N.A.: 0.65
Serial number: starts with "92"
Year of manufacture: 1992
Tube length: 160 mm
Parfocal length: 33 mm - so-called short barrel objective
Cover glass: yes, 0.17 mm thick
Immersion: no - this is a dry objective
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).

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.

LOMO exported its microscopes to Western Europe, where they were sold under the names Bresser Biolam / Bresser Erudit (mainly in Germany) and Zenith Biolam (in the UK). These microscopes often (but not always) came with special versions of the objectives without the "ЛОМО" engraving.

Apart from the missing manufacturer name, the export version also differs in the way the parameters are marked. On the LOMO version the marking read "МИ 90 1.25", where "МИ" is an abbreviation written in Cyrillic, corresponding to "MI" and meaning "oil immersion". The export version dropped the Cyrillic (and even the immersion information), and the marking changed to "A 90*1.25".

A note on the Bresser Erudit microscope: Bresser sold two different microscopes under this name. The first was a Lomo microscope labelled "Bresser Erudit", the second is the plastic, Chinese-made "Bresser Erudit DLX" microscope.
The microscope objective offered here fits the first of these two Erudit microscopes. A photo gallery of the first model can be found here: https://www.microscopeparts.eu/gallery/lomo-erudit-microscopes-207.
