Infrared optical lens component bidirectional transverse alignment processing method and equipment

Abstract

The invention discloses a two-way centering and processing method of an infrared optical scene component, which has the following processing steps: centering apparatuses are respectively arranged at the left side of a principal shaft of an lathe and on a tailstock of the lathe, with the shafts running oppositely to each other; a fixture chuck is arranged on the principal shaft of the lathe, and a scene component is fixed on the fixture chuck; simultaneously the center offset of two spheres is observed and repeatedly adjusts the center offset of spheres according to the observing information, until the two sphere centers satisfy the coaxal requirement correspondingly to the axes; the scene component is processed into a semi-finished products. The equipment of the invention consists of the lathe, a fixture chuck arranged on the principal shaft of the lathe, a first centering apparatus fixed on the tailstock of the lathe, a secondary centering apparatus fixed at the left side of the principal shaft of the lathe, and the first and secondary centering apparatuses are coaxal. The invention resolves the technical problems that images of two sphere centers cannot be observed simultaneously in the existing uni-directional centering and processing technique, and consequently the coaxiality of two sphere centers cannot be ensured to achieve the ideal optical axis, and the invention can ensure the autologous coaxiality of the sphere center of each optical scene component, as well as the coaxiality between optical components.

Description

technical field [0001] The invention relates to a processing method and equipment for an optical lens assembly, in particular to a processing method and equipment for an infrared optical lens assembly. Background technique [0002] The applicable spectral range of the infrared lens is 3-5μm. In order to finally obtain a clear and stable live image, the requirements for the coaxiality accuracy of the optical system are: the coaxiality of the spherical center of each optical lens assembly is less than 0.01mm; all optical lens assemblies are centered to ensure that the optical system coaxiality is 0.01mm ~0.03mm. The use of optical centering processing is to obtain an optical lens with high imaging quality. Optical centering processing is a mature process for visible light, and its centering accuracy can reach a coaxiality of less than 0.01mm. [0003] Visible light centering processing is to fix the optical lens assembly on the lathe spindle with special tooling on a high-p...
