The DH_PBSE_TE cooled lead selenide photodiode offers wide spectral responsivity to 5µm and the convenience of thermo-electric cooling.

Housing a 3x3mm active area lead selenide photodiode, the DH_PBSE_TE is operated in the photoconductive mode with the 215 high voltage supply whilst temperature control is ensured by the CPS1M.

Using an optically chopped input, the signal generated by this detector is best measured in using the 477 trans-impedance pre-amplifier followed by the 496 DSP lock-in amplifier.
