JETI spectraval 1501HiRes is a compact spectroradiometer for the visible spectral range for radiance measurement.

The high-resolution spectroradiometer spectraval 1501 HiRes was especially developed for the measurement of RGB laser projectors and displays. It has an optical resolution of better than 2 nm, so it allows a precise measurement of narrow bandwidth spectra. Its sensitivity is lower as of the standard version, but this is not significant in case of such light sources.
