Miniaturized light-weight design and preparation method of optical lens and optical lens

Abstract

The invention provides a miniaturized light-weight design and preparation method of an optical lens and the optical lens, and solves the problems that when the number of lenses of an existing optical lens is large, the assembly difficulty is large, time and labor are consumed, and the imaging quality is difficult to guarantee. The method comprises the following steps: 1) processing a corresponding mirror frame according to each optical glass, each mirror frame being a thin-wall structure, one end being provided with a first glue injection hole along the radial direction, and the other end being provided with a flange structure; assembling each piece of optical glass to the corresponding mirror frame, injecting an adhesive between the optical glass and the mirror frame, and forming each mirror group by each piece of optical glass and the corresponding mirror frame; 2) mounting the mirror frame on a centering lathe through the flange structure, finely turning the outer circle of the mirror frame, and cutting off the flange structure of the mirror frame; and 3) sequentially installing the lens groups in a lens barrel, arranging space rings between the adjacent lens groups, arranging a limiting structure at one end of the lens barrel, in the installation process, trimming the thickness of each space ring, and therefore, the optical interval between the two adjacent lens groups is guaranteed; and arranging a pressing ring at the other end of the lens barrel to axially pre-tighten and fix the lens group.

Description

technical field [0001] The invention relates to an optical lens structure design technology, in particular to a miniaturized and lightweight design and preparation method of an optical lens and the optical lens. Background technique [0002] On the one hand, the structural design of the optical lens is to provide support for the optical system, so that the optical system can complete its optical functions. On the other hand, it is necessary to ensure the imaging quality of the optical system through structural design. to miniaturization and weight reduction. [0003] A traditional optical lens structure design method is shown in figure 1 As shown, the optical system is composed of 7 pieces of optical glass 01 (lenses). The axial distance between adjacent optical glasses 01 is guaranteed by trimming the thickness of the spacer ring 02 between two optical glasses 01. The radial position of optical glass 01 is determined by The inner circle of the lens barrel 03 is guaranteed...
