A radial adjustment and fastening device for processing ultra-precision optical grazing incidence mirrors

Abstract

A radial adjustment and fastening device for processing ultra-precision optical grazing incidence mirrors, which relates to the field of optical design and manufacture, includes a fastening seat for mounting the mirror, a plurality of radial adjustment mechanisms installed on the fastening seat, and a Multiple glue blocks on the fastening seat; the radial position of the reflector in the fastening seat is adjusted by a radial adjustment mechanism; the circumferential position of the reflector in the fastening seat is adjusted by the glue blocks. Fastening the radial position of the reflector through the radial adjustment mechanism can effectively solve the sinking caused by the influence of gravity on the reflector during the processing process, improve the coaxiality between the axis of the mirror surface and the axis of the fastening seat, and at the same time The axiality should be controlled within 0.1μm, which improves the machining accuracy of the mirror surface. Two injections of glue through the glue block can increase the effective bonding area between the reflector and the fastening seat, improve the bonding force between the reflector and the fastening seat, play a role in stabilizing the fastening, and realize the mirror in the Radial fixation and circumferential fixation during machining.

Description

technical field [0001] The invention relates to the technical field of optical design and manufacture, in particular to an ultra-precision optical grazing incidence mirror processing radial adjustment and fastening device. Background technique [0002] X-ray astronomical observations are of great significance to the research of deep space exploration, space weather forecasting, high-precision automatic navigation of interstellar space flight and other fields. X-rays have the characteristics of short wavelength and strong penetrability. It is required that the X-rays received by the X-ray detector be grazing incident on the optical surface at a small angle to obtain a large reflectivity. The widely used grazing incidence optical systems mainly have three structures: K-B type, Wolter type and lobster eye type. The K-B type system has a relatively simple structure and is suitable for medium-resolution imaging and spectral observation of weak light sources. It has not yet been ...
