HgCdTe (MCT) Photoconductive DetectorPCI-2TE-13

1.0 – 15.0 µm, two-stage thermoelectrically cooled, optically immersed

PCI-2TE-13 is two-stage thermoelectrically cooled IR photoconductive detector based on sophisticated HgCdTe heterostructure for the best performance and stability, optically immersed in order to improve parameters of the device. The detector is optimized for the maximum performance at λopt = 13.0 μm. Cut-on wavelength is limited by GaAs transmittance (~0.9 µm). The device should operate in optimum bias voltage and current readout mode. Performance at low frequencies is reduced due to 1/f noise. 3° wedged zinc selenide anti-reflection coated (wZnSeAR) window prevents unwanted interference effects.
