We developed the Mavospec Base in order to make precise and easy photometry possible for everyone – whenever and wherever you need it. All measured quantities which are relevant for light such as illuminance, correlated color temperature, color rendering index according CIE 13.3 and IES TM-30-15, color coordinates in accordance with various CIE standards, flicker, spectral power distribution, peak wavelength, dominant wavelength and photosynthetic photon flux density are determined for the measured spectrum and displayed such that they can be understood by experts as well as laypersons.
