The PC-2TE-λopt photodetectors series (λopt – optimal wavelength in micrometers) feature IR photoconductive detec-tor on three-stage thermoelectrical cooler. The devices are optimized for the maximum performance at λopt. Cut-on wavelength is limited by GaAs transmittance (~0.9 µm).
Example of D* vs Wavelength λ for PC Series HgCdTe Detectors. Spectral Characteristics of individual detectors may vary from those shown on the chart.

MCT Photoconductive detectors
The packages of cooled detectors (TO8, TO66) are filled with dry, heavy noble gases for low thermal conductivity (Kr/Xe mixtures). Water vapor condensation is prevented by careful sealing and water absorbers applied inside the package. The packages are hermetically sealed with IR windows.
