Si-CAL Spectral Responsivity Standard (200-1100nm)

  • Si-CAL Si spectral responsivity reference standard connector
  • Si-CAL Si spectral responsivity reference standard 200-1100nm

Calibrated in our dedicated laboratory, in short-circuit conditions, with respect to standards calibrated by the Physicalish Technische Bundesanstalt (PTB, Germany), a range of calibration intervals within 200-1100nm is on offer.

Housing a 10x10mm active area silicon photodiode (200-1100nm), the Si-CAL delivers enhanced linearity and exceptionally low noise. Operated in the photovoltaic mode, the photocurrent generated by this detector is best measured in using a trans-impedance amplifier such as that of the Bentham 487 or 477.
