Abstract

The invention puts forward a micro-stress support structure of a large-caliber collimator reflecting mirror, thereby solving a technical problem that the surface precision of the reflecting mirror cannot be ensured effectively by the exiting collimator reflecting mirror supporting structure. A support scheme based on combination of a 3N-point flexible support part with one three-point flexible support formed by every three flexible support shafts, a central ball shaft support part, a lateral auxiliary support part is employed; the gravity of the reflecting mirror is unloaded; and the micro-stress support of the large-diameter collimator reflecting mirror is realized. Moreover, the surface precision of the reflecting mirror is guaranteed and the adjustment becomes convenient.

Description

technical field [0001] The invention belongs to the field of optical engineering and relates to a micro-stress support structure of a large-diameter collimator reflector. The large-diameter collimator reflector of the present invention refers to a collimator reflector with an aperture greater than or equal to 500 mm. Background technique [0002] At present, in the field of optical engineering, especially in the development of large-aperture collimators, the research on the support of large-aperture mirrors has become the focus of research. The gravity of large-aperture mirrors will cause large surface changes on the mirror surface. In addition, thermal changes and vibrations caused by surrounding environmental factors have a direct impact on the surface shape of the reflector, and the surface shape of the reflector is directly related to the index performance of the collimator. If there is a problem with the support form of the reflector, It will cause the collimator index...
