An optical device with a compensation of a thermo-optical effect of an optical component

The invention relates to an optical device (1) with a compensation of a thermo-optical effect, at least a first optical component (7) by means of at least one second, with respect to an optical axis (A) axially through an air gap (s In order to achieve a compact and passive compensation of thermo-optical effect, the at least two optical components (7, 8) by means of holders (11, 12) to a housing (4) determines at least one first optical component (7) by means of a on a perpendicular (s) to the optical axis (a) arranged bracket (11) and at least one second optical component (8) by means of one of the perpendicular (s) by a predetermined angle (α) deviating lever (15) containing the support (12) with depending an the air gap (s
