DH_PBS_TE Cooled Photodiode (1-3µm)

  • DH_PBS_TE detector 1-3μm
  • DH_PBS_TE lead sulphide detector chip
  • DH_PBS_TE detector with quick change adaptor
  • DH_PBS_TE detector with quick change interface

Housing a 3x3mm active area lead sulphide photodiode, the DH_PBS_TE is operated in the photoconductive mode with the 215 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.
