Spectral radiance / luminance calibration standards

Standard lamps calibrated in luminance and spectral radiance. Traceable calibrations in the wavelength range from 250 nm to 2500 nm.


Integrating sphere based standards (50mm to 500mm diameter) with tungsten halogen and LED sources (white, RGB-coloured and NIR).
