Radiance in a given direction, at a given point of a real or imaginary surface is the radiometric measurement quantity used to calibrate area sources of optical radiation. Gigahertz-Optik‘s calibration laboratory offers calibration of spectral radiance within the wavelength range from 250 nm to 2500 nm.

The calibration is done with a spectral radiometer equipped with a lens. The spectrometer system is calibrated with an integrating sphere based spectral radiance transfer standard.

The photometric quantity, luminance can be calculated using the radiometric calibration values from 380 to 780 nm if required.

A factory calibration certificate is supplied.
