Photoresistors based on lead selenide FR219-01, FR219-02, FR219-03
FR219-01, FR219-02 and FR219-03 are used in thermic automation and spectrum analysis equipment, fire fighting sensors.
The main advantage of these detectors is exclusively high sensitivity in infrared range, which is reached without cooling. They are widely applied in various fields of science and techniques and in military equipment, including homing head.
