Cross Grating Échelle Spectrograph

Application ID: 76151


This tutorial demonstrate the use of a Cross Grating feature in an échelle spectrograph. A cross grating is a periodic surface with two directions of periodicity. In this model the cross grating is used in high order in one direction and in first order in the orthogonal ("cross") direction. By this means a two-dimensional cross-dispersed spectrum can be produced with a single grating. A parametric sweep across several orders is made and the resulting ray and spot diagrams are generated.
