    Photos of Perkin Elmer Helium-Neon Lasers

    These are all really old HeNe lasers 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 a fat cable.

    The general internal construction of the unstabilised laser heads can be found in U.S. Patent #3,626,323: Thermal Stabilizing Arrangement for a Laser Device. Yeah, I know it has "stabilizing" in the title but don't be fooled! :)

    The principles of operation but NOT the internal construction for the Perkin Elmer 5800 stabilized HeNe laser is covered in U.S. Patent #3,793,595: Single Frequency Stabilized Laser.
