Abstract:

A simple derivation of the spectral resolution of the standard Perkin-Elmer prism and grating monochromators Models 12-C and 12-G has been carried out. Some attention is given to discussion of the variation of the diffraction pattern width at the exit slit as a function of the physical width of the entrance slit. Brief mention of power considerations is also made. The resulting formulas have been used to calculate spectral slit width curves for eight different prisms and twent-six gratings. The spectral slit width in 1cm is plotted as a function of the frequency in 1cm and wavelength in microns. These detailed graphs allow a determination of spectral slit width from quick inspection.
