A spectroradiometer JETI spectraval 1501-HiRes or spectraval 1511-HiRes can be used for the measurement of RGB laser projection.
The white signal of a RGB Laser projector consists of three narrow signals of red, green and blue, which form a large and impressive color gamut. It is helpful to use a spectroradiometer with a higher optical resolution for the calibration of such projectors. Therefore, JETI offers a special version of spectraval 1501 (or 1511) with an optical resolution of 2 nm (HiRes) instead of 4.5 nm. The measuring time of spectraval 1501-HiRes and spectraval 1511-HiRes is 4 times longer than the standard device spectraval 15x1. The application of such device allows a color setting with a higher matching to the visual impression.
