The Light Calibrator may be widely used in the laboratories where light from UV to IR range is applied in the experiments.

The Light Calibrator may serve to:

  • evaluate the total light power reaching the sample placed in the electrochemical cell assembled to the holder in the sample chamber.
    The Light Calibrator solves the problem of the precise measurement of the number of photons with a specific wavelength reaching the sample and the number of photons that are transmitted through the sample in the experiments performed with the Photoelectric Spectrometer.  The IPCE (Incident Photon to Converted Electrons ratio) may be precisely evaluated,
  • calibrate the light power of the LED source used in the  Microfedometer,
  • calibrate the light power on the sample in any experimental  setup,
