Stereomat viewers were manufactured in East Germany.
The version of Stereomat viewer below can be used to view
slides and cards and is manufactured from plastic. The white lenses can be
twisted for facilitate removal to allow cleaning. Images viewed through this
viewer are bright and clear. The viewer is very lightweight and easy to
Stereomat cards were made from
compressed paper and were not very robust, They easily showed signs of
wear or damage and required fairly gentle handling. The stereo effect of
these cards worked very well and individual images are
quite large at 20mm x 16mm. The cards themselves measure 104mm x 150mm.
This is a very simple viewer from around 1962
