IR photoconductive detector PC-LN2 series

HgCdTefor FTIR spectroscopyLN2-cooled

PC-LN2-14-1x1-VFP-NW-50 is a photoconductive IR detector based on HgCdTe heterostructures for optimal performance and stability. This detector is optimized for operation at cryogenic temperatures, typically at 77 K (liquid nitrogen temperature). Its 10% cut-off wavelength (λcut-off) is 17.4 µm and its active area (A) is 1 mm × 1 mm. The detector should operate in optimum bias current (Ib) and voltage readout mode. Performance at low frequencies is reduced due to 1/f noise. The detector is available in an especially designed flatpack package (without a window) for easy self-assembly in LN2 metal dewars. This detector is widely used in demanding applications requiring exceptional sensitivity and wide spectral range.
