I think the price is about $1200. Note that this is simply a broadband detector, with appropriate internal compensation for the sensor's sensitivity at the various wavelengths. Unfortunately precision light sources are considerably more expensive. Fortunately our fiber modems emit light continuously, and we use them for light sources.
