6:14 Dr. Erhard Glatzel (1925-2002), a mathematician at Zeiss, designed an f 0.7 lens for a NASA lunar mapping satellite, famously used by Stanley Kubrick to film the candle lit scenes in Barry Lyndon. The lens was based on a lens designed for a WWII German tank's night vision scope (the Zeiss UR-Objektiv 70mm f/1.0). Dr Glatzel found the earlier Zeiss lens design in the company's archives and improved the lens using, for the first time, computer aided design using an IBM 7090 mainframe computer. The NASA contract fell through, however, and an associate of Kubrick, Edmund DiGiulio, obtained about 10 of the mythical lenses. The unusual origin of the lens, a German tank's night vision system, meant DiGiulio had to cut off part of the lens mount and use a 0.7x condenser (reducing the focal length) in order to force the lens to fit the camera.

It uses a CV144 tube to produce the image and needs around 3000V to work. It was put in the same class as radio equipment (ZA 23001) because of how much power it consumed.

When I first joined the Infantry in the early 1990's (CA-ARNG) we had one PVS-5 per platoon, usually employed by either the Point Man or Platoon Leader. By the time I was deployed to Iraq in 2004 every member of our Infantry unit (1/69th, 256th IBCT) was issued either a PVS-7B or PVS-14, and we truly OWNED the night. Night vision gave the U.S. forces in both Iraq and Afghanistan a great advantage at night. Unfortunately, as these items became available to the commercial market, and similar units built by aggressor forces in China and Russia, that advantage has diminished and will continue to do so. That is one reason why U.S. has moved to Thermal Imaging, to give back the advantage of target detection in both day and night scenarios. SSG.
