The StellarNet model spectrometers are great tools for low cost, routine analysis of all types of light. From measuring the irradiance of standard light bulbs to measuring the exact color coordinates of the yellow in a traffic light, StellarNet spectrometers are used worldwide to routinely analyze light. These instruments are calibrated to measure the spectral irradiance in units of watts per meter squared over the wavelength range in nanometers provided by the selected spectrometer model. Currently, StellarNet offers Radiometer systems in the 200-1700nm range. The the bottom of the page details the various ranges for each StellarNet Spectroradiometer. The BLUE and GREEN-Wave models, BLACK-Comet concave grating model, and RED-Wave-NIR InGaAs model can be configured to have the correct slit size and detector array to suite your application. Calibrated spectroradiometers can be used to measure absolute intensity, xy chromaticity (CIE 1931), purity, correlated color temperature, and dominant wavelength.
