The Stereoflektoskop was introduced in 1913. It was based on the earlier Stereophotoskop but with the addition of a large ground glass finder with focusing adjustment. The camera was equipped with a push-pull magazine for 45 x 107 mm plates.

In 1923 a Compur shutter replaced the earlier Voigtländer design. Shortly after this a larger model for 6 x 13 cm was introduced. There are several minor variations in particular the viewing hood and front panel. The shutter speed and aperture dial positions vary between models. The Stereoflektoskop was the pattern for Franke & Heidecke's Heidoscop.
