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:

One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven Science Associates, a limited-liability company founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science and technology organization.
