UV/VIS/NIR радиометрия
Spectral Irradiance measurements can be done in different setups and wavelength ranges, like with fiber optic cosine corrector or integrating sphere. Irradiance measurements can be done in the UV, VIS as well in the NIR range.
For absolute irradiance measurements a spectrometer can be configured and radiometrically calibrated in the Avantes calibration laboratory with a range from 200 to 400 nm or from 350-1100 nm for a combined UV/VIS range of 200-1100nm, or for the 1100-2500nm range. This calibration is done on a fixed setup, i.e. fiber optics and diffusor can not be changed afterwards.
In order to be more flexible in the setup a calibration can be performed on location with a calibrated VIS/NIR light source (AvaLight-HAL-CAL) or calibrated UV/VIS/NIR light source (AvaLight-DH-CAL).
Our comprehensive AvaSoft-IRRAD software allows you to perform and load irradiance calibrations.
A typical setup for irradiance measurement is given below.
