About the company:

Wollensak Optical was an American manufacturer of audio-visual products located in Rochester, New York. At the height of their popularity in the 1950s and 1960s, many brands of movie cameras came with a Wollensak Velostigmat lens. Wollensak reel-to-reel tape recorders were prized for their robust construction and value. In the 1960s, Wollensak was the choice tape recorder for amateur home, school, and office uses. They were produced in both stereo and mono designs.

The firm was founded in 1899 by Andrew Wollensak to produce camera shutters. At its peak in the 1950s, it employed over 1000 people. The company had several owners, including Revere Camera Company and 3M Company. Wollensak ceased operation in 1972.

Wollensak began making camera lenses in 1902. The company also produced camera shutters for large format cameras. They made shutters such as the Betax, Alphax, Optimo and, for the Graflex Corporation, Rapax.

The Betax shutters were patented in 1912 and remain popular for large format photographers. Betax shutters are made in sizes from #0 to the huge size #5. These shutters are very reliable and relatively easy to repair.

Wollensak purchased the Fastax high speed rotating-prism camera developed by Bell Labs from Western Electric, and improved it to a rate of 10,000 frames/second. Fastax cameras were used for recording projectiles and explosions, including nuclear explosions. The cameras, with the rotating prism removed, were used for "streak" and "smear" photography.

Wollensak made only one still camera model, the "Stereo 10" 35 mm 3D camera.

They formed a partnership with the Revere Camera Company that led to them offering some movie cameras (mostly 8 mm) under their name in the 1950s and early 1960s. -- Source: Wikipedia --
