A flange assembly ( 1 ) of an optical system has a first flange ( 2 ), a compensation element ( 4 ) and a second flange ( 2 '). The flanges ( 2, 2 ') and the compensation element ( 4 ) are substantially axially symmetric both flanges ( 2, 2 ') being suitable for being connected to other components ( 10, 11 ) of the optical system in a non-destructive, non-positive axially separable fashion. The two flanges ( 2, 2 ') consist of different materials with different coefficients of linear thermal expansion. The compensation element ( 4 ) is radially soft, but connects the two flanges ( 2, 2 ') rigidly in their relative spatial position.
