Wollensak was an American company, based at Rochester, which manufactured lenses and shutters from 1899 to 1972. The company was founded by Andrew and John Wollensak.[1] It was bought by Revere Camera Co. in the 1950s,[2] itself absorbed by 3M in 1960,[2] and shut its doors in 1972.[3][1] A company named Surplus Shed currently holds the Wollensak factory building as well as some surplus.

Over the years, Wollensak produced a wide variety of lenses for still and movie cameras, projectors, enlargers, microfilm equipment, and military uses. Their better lenses were often labelled "Velostigmat", and their best lenses were labelled "Raptar". Like the Kodak Ektars, Raptars were often Tessar designs, though other formulae were used, particularly in wide angle and telephoto lenses.

At least one camera was sold with the Wollensak brand: the Wollensak Stereo 10 is a version of the Revere Stereo.
