In the previous sections we described equipment for production and dispersion of light into its component wavelengths. Here we describe detection systems. In a typical photo-research system, a detector measures the radiant intensity used to evoke photo-response in a sample or the radiant intensity produced by the sample in response to light or other simulation.
