Abstract

The invention discloses a cylindrical lens supporting device and optical equipment, the cylindrical lens supporting device comprises a supporting frame and a pressing assembly, the supporting frame is provided with an opening for light to pass through and a mounting hole for accommodating a cylindrical lens, the opening is communicated with the mounting hole, and the supporting frame is provided with a flexible table and three supporting tables which are all located in the mounting hole. The flexible table and the multiple supporting tables support the cylindrical lens, the multiple supporting tables define a supporting structure, the hole wall of the mounting hole abuts against the side wall of the cylindrical lens, the pressing assembly comprises flexible pressing blocks and multiple pressing blocks which are connected with the supporting frame, the number of the pressing blocks is consistent with that of the supporting tables, and the pressing blocks and the supporting tables are in one-to-one correspondence; the pressing blocks are used for pressing the cylindrical lenses on the corresponding supporting tables, and the flexible pressing blocks press the cylindrical lenses on the flexible tables. According to the supporting device, the cylindrical lens is pressed on the multiple supporting tables through the multiple pressing blocks, and the cylindrical lens is pressed on the flexible table through the flexible pressing blocks, so that multi-point press fitting is achieved, and the influence on the surface shape precision of the cylindrical lens is avoided.

Description

technical field [0001] The present invention relates to the technical field of optical equipment, in particular to a support device for a cylindrical lens and an optical equipment. Background technique [0002] In advanced optical equipment such as laser decoupling and laser mass transfer at home and abroad, in order to increase the spot energy density, reduce the width of the short axis of the spot, and avoid the overlapping area from being too large, it is necessary to use a large aspect ratio linear spot for scanning, resulting in large The aspect ratio linear spot is mainly realized by a high-precision 1-meter-level large aspect ratio cylindrical lens array, and part of the surface of the cylindrical lens is a free-form surface. However, the existing structure for supporting the cylindrical lens is prone to generate stress, which affects the surface shape accuracy of the cylindrical lens. [0003] In view of the above-mentioned defects, it is necessary to provide a new ...
