Abstract
The invention is directed to a stress-free support which includes two parts 1 and 2 having different linear thermal expansion coefficients. One part can, for example, be a mirror support made of Zerodur and the second part can be an aluminum support structure. A compensating stress-free support with flexure joints (121 to 126, 211 to 213, 214 to 216) increases the stiffness with respect to tilting. The stress-free support has a low weight and a low structural elevation. The entire arrangement is planar.
