    PR-655/670 User Manual HEORY OF PERATION The PR-655 and PR-670 are true Spectroradiometer. 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 48). The grating breaks up the light into its component wavelengths much like a prism turns white light into a rainbow.
