HgCdTe (MCT) Photoconductive DetectorPC-6
1.0 – 6.3 µm, ambient temperature
PC-6 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 = 6.0 μm. The device should operate in optimum bias voltage and current readout mode. Performance at low frequencies is reduced due to 1/f noise.
Features
