Method for installing optical element absence of stress

Abstract

The invention provides a method for installing an optical element absence of stress. The method includes the following steps that firstly, the optical element is stably put on an installation surface of a specific fixed subject matter; and secondly, when the resultant force of the optical element and the installation surface is zero, a connection material is symmetrically arranged at a junction of the optical element and the installation surface of the fixed subject matter, and the optical element is installed on the installation surface of the fixed subject matter through the connection material. The technical scheme of the method for installing optical element absence of stress has the advantages that 1, after the optical element is fixed on the installation surface, the inner stress is not generated, which cannot be realized in a traditional method; 2, after the optical element is installed, the inner stress is not generated and the fixation is firm through selection of proper connection material and connection technique; and 3, the method for installing the optical element absence of stress is concise and effective, and the practice verifies that the work is stable and reliable, and the method for installing the optical element absence of stress can be widely used for the optical element installation of various optical systems.

Description

Technical field [0001] The present invention relates to a method for installing optical elements, in particular to a method for installing optical elements without stress. Background technique [0002] In order to meet the high-precision and high-performance of precision optical equipment and instruments, it is necessary for the surface and thickness of the optical components in the optical equipment to have extremely high precision. The materials of the optical components have extremely high uniformity, few defects, and the spatial positioning of optical components High precision. [0003] At present, there are two commonly used methods for fixing optical components. One method is to fix the optical components with mechanical fastening force. The shortcomings of this method are: First: the mechanical fastening force applied to the optical element causes stress inside the fixed optical element, resulting in surface deformation, thickness change, uniformity change and even internal...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: first: the mechanical fastening force applied to the optical element causes stress inside the fixed optical element, resulting in surface deformation, thickness change, uniformity change and even internal stress damage and cracking of the optical element; Two: The optical components are affected by the external mechanical fastening force and internal stress and deviate from the preset spatial position, which affects the performance of the optical system

The disadvantages of this method are: first: the thermal expansion coefficients of the optical element, the connection medium, and the designated fixed object are different, and the optical element will generate internal stress due to differential expansion or differential contraction after fixing; second: the optical element is in the process of connection. The uneven shrinkage or expansion of the connection medium with the fixed object causes the internal stress of the optical element and deviates from the preset spatial position
