Mechanical clamp for clamping optical lens

Abstract

The invention provides a mechanical clamp for clamping an optical lens. The mechanical clamp comprises a base, two moving assemblies, two clamping assemblies, a lead screw assembly and a clamping head. The two clamping assemblies are driven by the lead screw assembly to move synchronously in the reverse direction to adjust the clamping heads with high precision, the clamping precision of the whole clamp can be guaranteed, the stress unevenness of the two sides of the optical lens in the clamping process can be eliminated, stable clamping and installation of the optical lens are achieved, and the clamping device has the advantages of being low in cost and high in stability.

Description

technical field [0001] The invention belongs to the field of optical applications, in particular to a mechanical clamp for clamping optical lenses. Background technique [0002] Semiconductor lasers, which use semiconductor materials as working substances, have broad application prospects in optical communications, optical storage, and laser processing due to their small size, light weight, and ease of use. Therefore, since the semiconductor laser uses an asymmetric active channel, the laser beam emitted by the end face has a large divergence angle, which can be as high as θ=20° and θ=60° in the parallel and vertical directions. Therefore, the beam collimation of the semiconductor laser becomes an indispensable step. [0003] At present, in the beam collimation process of semiconductor lasers, since the semiconductor chip and the corresponding collimating lens are relatively small in size, slight installation errors will cause beam collimation failure, and the installation ...
