DPbS series PbS Detectors
PbS detectors application

· DPbS2900 and DPbS3200 are the photoconductive IR detectors, which must be used with lock-in amplifier.
· DPbS2900 and DPbS3200 detectors integrate the pre-amplifier, the detectors output signals are voltage signals. When working with DCS103 or DCS300PA, the detectors needs choosing voltage signal as the sampling mode

Room temperature IR detectors, spectral range from 0.8 to 3.2_m. DPbS2900 and DPbS3200 have the same construction (built-in pre-amplifier).
