Photoresistors based on lead selenide FR224, FR224-01, FR224-02, FR224-03
FR224, FR224-01, FR224-02 and FR224-03 are intended for gas analyzers and thermal radiation detectors.
Photodetector is cooled by one-cascade thermoelectric cooler (TEC).
The cooling of photodetectors by TEC allows to determine thermostabilisation mode, due to this mode dependence on environment may be eliminated.
