Gossen Mavospec Base

The Mavospec Base is a hight-quality, miniaturized spectrometer for routine daily measurement of al conventional and modern light sources such as LEDs and OLEDs.

All characteristic measured quantities such as illuminance, correlated color temperature, color rendering index, color coordinates in accordance with various CIE standards, flicker, spectral power distribution, peak wavelength and dominant wavelength are determined for the measured spectrum and displayed such that they can be understood by experts as well as laypersons.
