Check these pictures out for #TBT; a Thermovision 680 Liquid Nitrogen cooled system circa 1968 that was utilized for medical applications.Originally manufactured by AGA Infrared Systems of Sweden, the camera had interchangeable lenses and a Polaroid camera attachment that was used to capture the infrared images shown on a display unit (not seen here) as there was no on-board file storage.
The "Short Wave" model used a single InSb (Indium Antimonide) detector while the Long Wave version featured a HgCdTe (Mercury Cadmium Telluride) detector.
