Elgeet Cine Stereo beam splitter and projection lens combination for 16mm film cameras of the 1950s

Are you talking about using a beam splitter? The adapter fits over a lens, it is eye width adjusted, so with one camera two stereo images are taken.

Familiar with the beam splitters. I have often used the Stereo Tach in the early high school days with a single film camera. ( You may be interested in how some DIY ers modified the device by ungluing the front first surface mirrors so they can swing for closer stereo window for closer objects, had to be pried lose,,,. i bought the more recent Franka splitter which is cheaper device using back silvered mirrors (less crisp, never liked it at all). I recall there was a nice Pentax model ( prisms?) that was presumed better than most. Of course Leica made a great prism splitter for its cameras. Actually several, from 1930s onward for a 50mm lens.....As a side mention, I also did a few 16mm movie stuff with the Elgeet optical splitter and lens device. Remember home movies .gents and ladies ?? As with all these fixed mirrors, the images were tall and narrow and there was a hard to control space in the middle. But they represented a cheapo way to get into stereoscopy. Beyond the cha cha of still objects that is. Photo: A stereo 16mm clip w the vintage Elgeet Cine Stereo beamsplitter/ lens combo. Elgeet made a projection lens with pola filters for screening these kind of shots..,..yes, the old old days of the roaring ha ha fifties..  One fatal defect= the fifty percent loss of projection light from the plane polarizers of that time.  Film did not like super hot projection bulbs either....cinema was not my specialty.  But there are some good histories on line if you look them up.
