Paper Abstract

The novel spectrometer here scans the path difference that is introduced between two beams that are produced with wavefront division by variation of angle of incidence on a reflection lamellar grating of fixed groove depth--not variation of groove depth at normal incidence, which is impractical for the near infrared owing to friction. Performance of a shallow groove grating is presented, and performance of a deep groove grating is predicted. An application of transparent lamellar gratings, with telescope objectives, is described.
