Abstract
Thermally compensated optical assembly comprising a monolithic mount which is divided by slits into a mounting ring and at least three elastic links which are connected to an optical element. The elastic links compensate the thermal expansion differences between the mounting ring and the optical element through deformation. The temperature-dependent reaction forces brought about by the deformation are compensated. For this purpose, the quantity of compensation elements is equal to the quantity of links. The compensation elements comprise in each instance an expansion body and a spring element.
