Abstract

The invention provides a lens stress-free adjusting device and method suitable for a nested grazing incidence focusing optical lens. The lens stress-free adjusting device comprises a horizontal adjusting assembly (1), a vertical adjusting assembly (2), a lens fixation assembly (3) and an optical platform (4). A lens (5) fixed by the lens fixation assembly (3) is adjusted in position and pose through the horizontal adjusting assembly (1) and the vertical adjusting assembly (2), and then, adjustment of optical axis eccentricity, inclination and axial errors of the lens is realized through six steps of gravity compensation, horizontal adjustment, height lifting, radial plate gluing, height reduction and glue filling bonding. The lens stress-free adjusting device solves the problems that a conventional lens stress-free adjusting device is large in lens adjustment error and is not suitable for the nested grazing incidence focusing optical lens in the prior art, and is high in adjusting precision, good in stability and high in university.

Description
