These are names commonly used to refer to this manufacturer of microscopes and microscope parts, even if they are not official. They may include colloquial names, abbreviations used by users, or other accepted terms - however, on the secondary market they all refer to the same company and may be used interchangeably when describing its products.

# Belongs to category:
Condensers

# Description and specifications:
Special diaphragm in holder for the polarizing condenser of the Lomo Polam microscope.

Together with the Lomo Polam polarizing microscope, a set of five such 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 special diaphragm with a small light aperture. 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.
