Compact broadband (VIS/NIR) spectroradiometer with imaging grating, offering a variety of applications. The device measures spectral luminance and illuminance, chromaticity coordinates ((x,y), (u',v')), correlated color temperature, color purity, color rendering index, RGB, circadian metrics and photosynthetically active radiation, with a 4.5nm optical resolution (FWHM) and a USB 2.0 fullspeed interface on the standard model ; additional Bluetooth, LAN or RS232 interfaces can be added.
