Reflectance, Transmission and absobance measurements are always performed in a small integrating sphere, a spectrometer and certified standards are used to perform the measurements.

The energy reflected or transmitted through the sample is fully integrated before reaching a baffled detector assembly. The reflectance is weighted and integrated by the CIE Standard Photometric Observer Function.

The spectrometer offers a measurement range covering the visible region of the spectrum from 380 to 780 nanometer.
