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.

Description of this part for the microscope.

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.

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

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).

In the last photo in the gallery you can see a page from the Lomo Polam microscope manual where this element is shown. In the manual it is shown in figure number 6, element number 65.

with the Lomo Polam polarizing microscope. The set included phase contrast diaphragms and dark field diaphragms. Here I present and offer a complete set.

Important note:

These diaphragms are mounted onto the polarizing microscope condenser to obtain a combination of these techniques and a phase image in polarized light. Please note that the same condensers can also be used in polarizing microscopes of the Lomo MIN series (for example Lomo MIN-6 or Lomo MIN-8 models) and in microscopes designed for infrared light work from the Lomo MIK series (for example Lomo MIK-4). This means that there is nothing preventing the use of these phase rings in those microscopes as well.

The latest version of the Lomo Polam microscope, namely the Lomo Polam LMPR model, no longer requires this accessory. The Lomo Polam LMPR already features a dedicated rotating polarizing phase condenser (somewhat similar to the Lomo KF-4 condenser).

The last photo in the gallery shows a page from the Lomo Polam microscope manual where this microscope part is presented. In the manual it is shown in figure number 6, item number 65.

If you have such a set but it is incomplete - browse this database - you will also find individual diaphragms offered separately - specifically to solve such situations.
