DH_PY Pyroelectric Detector (1-30µm)

  • DH_PY pyroelectric detector with a KRS5 window 1-30μm

Housing a 2x2mm active area pyroelectric detector fitted with a KRS5 window (1-30µm), the DH_PY includes an integrated impedance matching amplifier. The amplifier is powered by the DH_PY_PSU module. The signal generated is best measured in using the 496 DSP lock-in amplifier.

The mounting flange supplied with the DH_PY is compatible with the entire range of Bentham monochromators and accessories.
