Handheld light spectrometer MAVOSPEC BASE – Gossen Metrawatt

MAVOSPEC BASE from Gossen Metrawatt is a compact handheld spectrometer for precise light qualification and documentation. It derives key photometric, colorimetric and spectral parameters from the measured spectrum, including illuminance, CCT and Duv, CRI (CIE 13.3), IES TM-30-20 (Rf/Rg), TLCI, chromaticity coordinates (CIE 1931/1960/1976), flicker, spectral power distribution, peak/dominant wavelength and PPFD. Results are displayed clearly for fast on-site evaluation and reporting.
