Abstract
A mirror adapted for compensating thermal distortions resulting from the absorption of energy in a beam of radiation incident thereon is disclosed. Coolant channels disposed within the mirror proximate the reflective surface are adapted for passing coolant therethrough to minimize the temperature rise in the mirror resulting from the absorbed energy and the resulting thermal distortions therein. Heating channels disposed within the mirror proximate the back surface are adapted for passing a heating fluid therethrough for increasing the temperature of the back surface to induce thermal distortions therein, said induced thermal distortions having a direction and magnitude to counter the distortions resulting from the absorption of radiant energy at the reflective surface of the mirror.
