Paper Abstract

The limit of resolution for the planar varied line-space grating in a converging beam can be found by analyses of the optical path errors. The errors may be canceled by slight deviations of the planar substrate surface. The cancellation of the path errors leads to a markedly improved spectral resolution. The surface figure for an improved resolution deviated planar varied line-space grating spectrograph is shown. Ray-tracing of this improved spectrograph shows substantial gains in spectral performance.
