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:
A set of five special diaphragms in a holder for the polarizing condenser of a Lomo Polam microscope.

A set of five such special diaphragms was supplied together 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:
Such diaphragms in a special holder were supplied as a set of five diaphragms as an accessory for the Lomo Polam polarizing microscope. 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.

# Examples of use
- if you have a compatible Lomo condenser and want to use this special phase contrast diaphragm
- if you want to combine several observation techniques, for example polarization and phase contrast at the same time
