Numerical Aperture: 0.65
Tube: 160 mm
Focal Length: 33 mm
Cover Glass: Yes, 0.17 mm
Thread: RMS + Pol adapter
Info: P = Polarization

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

The RMS thread objective is mounted on a suitable insert, allowing it to be used with Lomo Polam, Lomo MIN-1 / Lomo MIN-6 / Lomo MIN-8 microscopes. Of course, the objective can be unscrewed and a different objective screwed into the insert.

The Pol adapter also allows you to center the objective lens along the entire optical path - but this requires tools.

Note: I've seen numerous reports claiming this RMS-Pol adapter is compatible with Leitz Wetzlar polarizing microscopes - but I haven't personally verified it.

This objective is for use with transmitted or reflected light with a cover slip (although I am not sure if it definitely requires a cover slip).

This specific item was used with the Lomo Polam P-312 microscope, i.e., with an EPI reflected light illuminator.

The RMS-thread objective is mounted on a suitable sleeve that allows using the objective in 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.

and focusing is achieved by raising or lowering the microscope stage. This is the opposite of how it works, for example, in the Lomo Biolam model, where the arm moves up and down.

Along this rack gear offered here, the entire assembly of the microscope stage holder and the condenser is moved. This assembly is driven by a gear wheel mounted on a shaft located between the coarse focus knobs.

This is an original brass rack gear, not a plastic 3D print. The set includes two mounting screws (the upper and lower ones differ from each other).

polarizing microscope LOMO MIN-8

Description of this part for the microscope.

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

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.

Mount diameter: 35 mm

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 Pol 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 Pol filter of low N.A.
This element is often used by owners of microscopes from other manufacturers to convert their condenser into a polarisation 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.

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.

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.

special diaphragms was supplied. The set included phase contrast diaphragms and dark field diaphragms.

Note - I am showing and offering here one single diaphragm in holder - exactly the one visible in the photos. This is a phase contrast diaphragm (phase annulus). The complete set for the Lomo Polam microscope contains 5 diaphragms.

Important note:
Such diaphragms in a special holder, supplied as a set of five diaphragms, were an accessory for the Lomo Polam polarizing microscope. These diaphragms are mounted onto the polarizing microscope condenser in order to combine these observation techniques and obtain a phase image in polarized light. Please note that the same condensers can also be used in Lomo MIN series polarizing microscopes (for example Lomo MIN-6 or Lomo MIN-8 models) and in Lomo MIK series infrared microscopes (for example Lomo MIK-4). This means that there is nothing preventing the use of these phase annuli in those microscopes as well.

The newest version of the Lomo Polam microscope, namely the Lomo Polam LMPR model, no longer requires this accessory. The Lomo Polam LMPR already has a special polarizing phase contrast disc condenser (somewhat similar to the Lomo KF-4 condenser).

After installing a 12 mm adapter, this combination of adapter and objective will function as an objective with FL=45 mm.

This objective is attractive mainly to collectors because:
- there are very few microscope objectives with the LZOS logo on the secondary market
- the objective has a so-called "golden serial number": 01234

Manufacturer: Lomo
Model: PLAN 25x0.50 P
Original designation: ЛОМО ПЛАН 25х0,50 П
Magnification: 25x
Numerical aperture N.A.: 0.50
Tube length: 160 mm
Cover glass: yes, 0.17 mm thickness
Immersion oil: no – this is a dry objective
Focal length: 45 mm
Thread type: RMS
Additional designation: P (Cyrillic: П) indicates that this objective is designed for use with polarized light
Special features: built-in iris diaphragm
Year of manufacture: 1976

This objective has a standard RMS thread and TL=160 mm, which means it can be used with the vast majority of microscopes from virtually any manufacturer, including Olympus, Zeiss, Nikon, PZO, Carl Zeiss Jena, Reichert, Wild and many others.

The built-in iris diaphragm allows, among other things, precise centering of the objective, because in a polarizing microscope the following diaphragms may operate simultaneously:
- field diaphragm in the illuminator
- aperture diaphragm (or two aperture diaphragms) in the condenser
- iris diaphragm in the microscope objective
- iris diaphragm in the eyepiece head
and accurate centering of all of them relative to each other is very important in polarized-light observations.

Objectives marked "P" / "Pol" feature a special construction in which the lenses are mounted and cemented in a way that prevents mechanical stress. They can be used both for conventional brightfield microscopy and for observations in polarized light.
