Py-CAL Spectral Responsivity Standard (1-30µm)

  • Py-CAL Spectral Responsivity reference Standard 1-30µm

Calibrated in our dedicated laboratory, with respect to standards calibrated by the Physicalish Technische Bundesanstalt (PTB, Germany), a direct calibration to 20µm with an extension to 30µm is on offer.

Housing a 2x2mm active area DLATGS pyroelectric sensor fitted with a KRS5 window (0.6-40µm), the Py-CAL reaches parts of the infrared for which no photon detectors are available. Operated with the DH-PY-PSU power supply module with a low frequency chopped input, the signal generated by this detector is best measured in using the 496 DSP lock-in amplifier.
