Lens mount integrated with a thermoelectrically cooled photodetector module

An integrated housing for a lens and a photodetector, which is being cooled to low temperatures to enable the detector to detect faint emission of photons. An enclosure is provided to which a lens is affixed from one side using a retaining ring, and a photodetector is affixed from the opposite side....

Beschreibung
Zusammenfassung:	An integrated housing for a lens and a photodetector, which is being cooled to low temperatures to enable the detector to detect faint emission of photons. An enclosure is provided to which a lens is affixed from one side using a retaining ring, and a photodetector is affixed from the opposite side. The enclosure is affixed to a TE cooler. The enclosure and the retaining ring are made from materials having similar thermal expansion coefficients.
