Polyscop cameras are a series of stereo plate cameras made in the 1910s and early 1920s by ICA. Both a rigid-bodied and a strut-folding version were offered. Some of the cameras have a waist-level finder, with its lens in the lens board, between and below the two taking lenses, so that the camera looks rather like the Stereflektoskop or the Heidoscop. It is not clear whether this finder gives reflex focusing; all the cameras have helical focus with a lever behind the lens board. There is also a folding direct-view finder (a Newton finder) mounted on most examples seen. The example linked below at Leitz Photographica Auction does not have the Newton finder, but this camera has definitely been modified; it also has a custom-made roll-film back instead of a plate holder or magazine.

- Examples at Sylvain Halgand's Collection Appareils (French text):
- Polyscop for 45x107mm plates, with 60mm f/4.5 Optis Paris anastigmat lenses. Strut-folding body (which saves very little space when the camera is fitted with the twelve-plate magazine).
- Polyscop for 6x13cm plates, with 9cm f/4.5 Tessar lenses. Rigid body; much the same specification as the camera illustrated here, but placement of the shutter speed, aperture and viewfinder are all different! With twelve-plate magazine.
- Polyscop sold at the 36th Leitz Photographica Auction, on 13 June 2020. Customised with permanently-attached roll-film back for 120 film, though the camera is plainly originally for 45x107mm plates. 62mm f/4,5 Tessar lenses, apparently with sliding aperture plates, not an iris diaphragm. No direct-view finder (but this could have been removed with the customisation). With tripod bush and bubble level on both the top and the bottom!
