    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.

    I recall small plastic IR detector cards for testing remote controls and the like; they had to be 'charged' in visible light, and would emit reddish-orange (to my eyes) glow in presence of IR.

    I think you have a technical error -- 3nm is nowhere near infrared... I think you meant 3 micron (um) which would be "fairly long IR" ... (900 nm is a typical IR LED like a remote control might use;
    685 nm is a common red LED; 450 nm is a typical blue LED )

    I have a pair of type E tabby night vision binoculars that technically still work, though I haven’t tried them since they’re over 80 years old now. I don’t know how many are left today, they only ever made 3000 of them, and many were destroyed during and after the war. I would guess less than 1000 remain. 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.

The screen is then rotated into the optical field of the scope for use.

    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.

    As I understand it the British had the first fully operational night vision at the start of WWII, with the "TABBY" RG receiver.

    Every time I hear the capacitor charge on gen 1 NVG as it powers up, I think of the movie "Silence of the Lambs" whenever they're used by "Buffalo Bill".

    6:41 Do you mean 3 microns? 3 nanometers is an X-ray wavelength rather than infrared.
