Zeiss Ikon Steritar is a stereo attachment (beam splitter) allowing to take stereo picture pairs.

The adapter consists of body (made of anodized aluminium) and bronze insert secured by means of 3 set screws. Such design allows angular adjustment and alignment of the attachment on any particular lens.
