Low-tension optical bench with thermal decoupling

A device for arranging optical components in a housing, comprising:

• a housing;
• an optical bench formed in one piece from a rigid material having a high thermal conductivity and yield strength;
• at least two spring elements at the outer edges of the optical bench, the spring elements acting in the plane of the optical bench, wherein the optical bench is fastened to pedestal elements of the housing exclusively by means of the spring elements, and the optical bench is self-supportingly held in the housing by means of the pedestal elements;
• clamping bars below the spring elements;
• thermal isolators below the clamping bars, wherein the clamping bars rest at least in portions on the thermal isolators, and the clamping bars can be stably supported thereby relative to the pedestal elements of the housing;
• and
• a thermal strap, wherein a first end of the thermal strap is fixed to a self-supporting region of the optical bench, and a second end of the thermal strap is fixed between a pedestal element and a clamping bar next to a thermal isolator.
