    Chapter 3 – Theory of Operation Chapter - 3 T HEORY OF PERATION The PR-7XX are true Spectroradiometers. They collect the optical radiation (light) through the objective lens or other optical accessory. The signal then passes through the aperture (hole) in the aperture mirror to the diffraction grating (see Figure 18).
