Echelle efficiencies - Theory and experiment
Abstract
The effect of one echelle spectrograph design factor, orientation of the incident light bundle, is examined. Comparison of theoretical calculations and experimental measurements of echelle grating efficiencies are given for R2 echelles used in three possible configurations: alpha greater than beta, alpha smaller than beta, and the quasi-Littrow mode. The throughput-resolution products for these various cases are also compared.
