DH_PBSE_TE Cooled Photodiode (1-5µm)

  • DH_PBSE_TE Cooled Photodiode Detector

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.
