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 min of arc, whereas the f/10 subsecond of arc imaging spectrograph has a field of view of 3 armin. They are to be commissioned in 1991.
