Paper Abstract

In an Offner spectrometer, unlike other spectrometers, the dispersion need not be in the plane of the instrument (defined as the plane that includes the mirror vertices and the center of the entrance slit). If the entrance slit is short, better performance can be obtained when the dispersion is perpendicular to this plane. The reasons for this are briefly discussed, and design examples given.
