The is a really old HeNe laser made by Perkin Elmer. It consists of a two-Brewster tube with a heated filament in a laser head enclosure that looks like something out of a James Bond flick. A separate power supply about the size of a PC mini-tower attaches via fat cable.
This is a later model power supply that runs a lsaer head virtually identical to the 5200, above. It's about 1/10 the size and weight!
This is a very early model Perkin Elmer HeNe laser power supply. The identify of the mating head is unknown but based on a 1968 brochure, it had a minimum rated output power of 1.0 mW (1.5 mW typical), divergence of 0.8 mR (full angle), and an expected life of 4,000 hours. The cost of the system in 1968 was $295.
