Method for adjusting optical axis consistency of multi-optical-path lens

Abstract

The invention provides a multi-optical-path lens optical axis consistency adjustment method, and solves the technical problems that the optical axis consistency and the imaging quality are difficult to guarantee at the same time, the optical axis consistency adjustment precision is low, and the product production efficiency is limited in the existing adjustment method. The adjusting device comprises a dual-channel internal focusing light pipe and a reticle which is installed at a convergent light beam exit port of a lens to be debugged and located on a focal plane of the lens to be debugged. The reticle is precisely matched with a mechanical axis of a to-be-debugged lens, and the center of the reticle is the optical axis of the to-be-debugged lens. According to the adjustment method, the deviation of the consistency of the optical axes of the two lenses is measured by using the focusing light tube and the differentiation plate in the dual-channel, and then a certain adjustable optical element in the to-be-debugged lens is adjusted, so that the adjustment of the consistency of the optical axes of the multi-optical-path lens is realized, the accumulated error of a traditional adjustment method is reduced, and the adjustment precision of the consistency of the optical axes is improved.

Description

technical field [0001] The invention belongs to the technical field of precision optical instruments, and in particular relates to a method for adjusting the consistency of optical axes of multi-optical-path lenses. Background technique [0002] Laser, infrared, visible light and other multi-optical lens devices are widely used, and the optical axes of each optical sensor must be consistent to work effectively. Therefore, ensuring the optical axis consistency of each optical sensor is an important technical index of a multi-optical lens device. [0003] The traditional optical axis adjustment method is to simulate the optical axis of the lens through the reticle, and after the axis of the reticle at each position is aligned, the optical axis adjustment of the lens is completed. This adjustment method has certain limitations. First, due to the existence of assembly and adjustment and processing errors in the multi-optical lens of the common optical element, it is often diffi...
