Optical design of two spectrographs for the Canada-France-Hawaii telescope.
Abstract
Optical designs of two new spectrographs for the Canada-France-Hawaii telescope Cassegrain focus are described. Also given is a summary of the design procedure using the Dominion Astrophysical Observatory optical design code OPTESA (optical system optimization by educated simulated annealing). The f/2.8 multiobject spectrograph has a field of view of 10', whereas the f/10 subsecond of arc imaging spectrograph has a field of view of 3'.
