description

The light calibrator serves as photoradiometer of total light power reaching a sample attached to our universal photoelectrochemical cuvette. It fits right behind the output window of the cell and captures all the light passing through this part of the sample that has contact with an electrolyte.
The device solves the problem of a precise measurement of number of photons reaching the sample at a given wavelength. It is complementary tool to a photoelectric spectrometer equipped with IPCE (Incident Photon to Converted Electrons ratio) module. The module records the total light output of the spectrometer. Only fraction of this output reaches the sample. And that fraction is precisely estimated using the absolute IPCE calibrator.

The calibrator can be also employed as light intensity gauge for LED revolver in a mini photoelectric spectrometer.

Calibrator head for 30 mm cage system

 

 

The head is armed with NIST traceble calibrated photodiode with active area of 1 cm2, that measures light power passing through the output window of the universal electrochemical cell.
