Spectroscopy Detectors - DPbS Series


PbS Detector

The PbS detector is a room temperature IR detector with a spectral range from 0.8 to 3.2 μm.

DPbS2900 and DPbS3200 have the same construction (built-in preamplifier).

  • DPbS2900 uses the import PbS Detectors (Spectral response curve, see Fig.1)
  • DPbS3200 using the general PbS detectors (Spectral response curve, see Fig.2)

PBS Detector Application Advice

DPbS 2900 and DPbS 3200 are the photoconductive IR detectors which must be used with lock-in amplifier. SR 830 or Model 420 is recommended.

DPbS 2900 and DPbS 3200 detectors integrate the pramplifier, the detectors output signals are voltage signals. When working with DCS 103 or DCS 300PA, the detectors need to choose voltage signal as the sampling mode.
