IR Detector (HgCdTe detector: HCT 16-18)
IR Detector (HgCdTe detector: HCT 16-18) has peak sensitivity at 16-18microns, 50% peak sensitivity at 9 microns, 25% at 4.5 microns, 12.5 at 2.25 microns. Also, it has an impedance 10-50ohms. A photo-conductive detector needs bias voltage, depends on detector size. The size of detector is between 2/1000 to 100/1000 square inches, bias is 1V, 40mA for 1mm square. The detector pre-amp(110) includes bias rise time 100-150 ns. The orange window is KRS5 window, flat 70% transmission from 2 to 25 microns.
The measured spectral response of the red detector is shown in the following figure:
