Calcium Fluoride Infrared Optical Components
index of refraction allow Calcium Fluoride to be used in systems without the use of antireflection coatings, unlike other IR materials. Optics for Cryogenically Cooled Thermal Imaging: Cryogenic cooling is required for cameras where a semiconductor material is used in the camera system. Cooling of the camera system is cooled from anywhere between 4 Kelvin to just below 20 degrees. Without this cooling the camera would suffer from interference created by the heat created by the camera system... (read more)

MICRO:New Technologies-Analysis & Metrology, by Patrick J. McCann, p.93 (July '99)
to the commercialization of mid-IR lasers that can be operated with thermoelectric cooling modules. These new lasers will be much more economical than current devices, which must be cryogenically cooled. Consequently, they should find cost-effective uses in a variety of semiconductor manufacturing processes in which
