COS Optical Layout. FUV and NUV channels initially share a common path. The first optic is either a concave, holographically ruled diffraction grating that directs light to the FUV detector (red) or a concave mirror directing light to the NUV gratings and the NUV detector (purple). The green colored ray packets represent the FUV optical paths, and blue colored ray packets represent the NUV optical paths. A wavelength reference and flat field delivery system is shown at top left (orange ray packets) and can provide simultaneous wavelength reference spectra during science observations.
