Zeiss Ikon Ortho-stereoscope

Germany, 1930s

This stereoscope from late '20s/early '30s has pinions for making adjustments, movable slats to hide the center, an adjustable frame for different formats and a removable handle. The design is based on the ortho-stereoscope from Ica, which merged with some other companies in 1926 to form Zeiss Ikon.
