HgCdTe (MCT) Photoconductive Detector

PC-5

1.0 – 5.4 µm, ambient temperature

PC-5 is uncooled IR photoconductive detector based on sophisticated HgCdTe heterostructure for the best performance and stability. The device is optimized for the maximum performance at λopt = 5.0 μm. The device should operate in optimum bias voltage and current readout mode. Performance at low frequencies is reduced due to 1/f noise.
