LOMO Polam P-113 Polarising Microscope

Posts relating to the use of the LOMO Polam P-113 Polarising Microscope. This is an old Russian Federation Microscope – solidly made with rotating stage, crossed and plain polarising filters, and (in Andy’s model May 2018) an LED-modification to the built-in illuminator.

Ritland Impactite – “first light” with LOMO Polam P-113 Polarising Microscope

The following photos are from a slide of Ritland Impactite seen through the LOMO Polam P-113 Polarising Microscope. The four photos show the changing colour of the crystals as the polarising filter in the condenser is turned through 90 degrees. There is another polarising filter in the eyepiece assembly. Hence, this slide is being seen with “Crossed Polarising Filters”.

Information on the LOMO Polam P-113 Polarising Microscope can be found here, http://roslistonastronomy.uk/lomo-p-113-polarising-microscope

The following is a video of the same slide through this microscope – showing effect of rotating the polarising filter in the condenser, rotating the rotating stage, and X-Y movement of the stage.

LOMO P-113 Polarising Microscope

The LOMO P-113 Polarising Microscope is an old Russian Federation microscope – solidly built, this one comes with an LED modification to the illuminator and a trinocular head and monocular head. I have used the monocular head in the trinocular port of the trinocular head to allow simultaneous photography and visual observation. There is lever on side of the trinocular head to change between visual and photographic use.
