1. An infrared camera having:

  • optical assembly (71) which brings light/infrared radiation to a focal plane array (33) of infrared sensitive microbolometers on a semiconductor substrate (30) that is maintained constantly at any selectable temperature, over a wide range, by a thermoelectric temperature stabilizer (20) wherein said thermoelectric temperature stabilizer is regulated by a controller (73) which maintains temperature based on a signal received from a temperature sensor (27) in close thermal association with said array.
