Abstract

The invention belongs to a zoom system assembly and adjustment method, in order to solve the existing zoom lens assembly method because the method for determining the focal plane position of the zoom lens is cumbersome, and the imaging quality cannot be controlled in the middle of the assembly process, resulting in low efficiency of zoom lens assembly and adjustment. The method for quickly determining the surface area is cumbersome, and it needs to rely on the technical problems of the image detector to provide an assembly and adjustment method for the continuous zoom system, including the assembly of the lens in each zoom component of the zoom lens, the imaging quality inspection and adjustment of each zoom component, The final assembly of the zoom lens, the determination of the zero position of the focus and the position of the image plane of the zoom lens, the docking of the image plane of the detector, the penetration of the zoom lens, and the calibration of the position of the zoom cam curve.

Description

technical field [0001] The invention relates to a method for installing and adjusting a zoom system, and specifically provides a method for installing and adjusting a continuous zoom system. Background technique [0002] The application of zoom lenses has been in use for decades. With the development of modern society and the advancement of science and technology, continuous zoom optical systems have been widely used in various fields, such as security, monitoring, skynet, transportation, production safety and forest fire prevention. The optical path of the zoom lens is generally composed of a front fixed group, a zoom group, a compensation group and a rear fixed group. When assembling the entire lens, there are both moving groups, such as the zoom group and compensation group, and fixed groups, such as the front fixed group and the rear fixed group. The assembly is relatively complicated. Therefore, the fast and high-quality assembly and adjustment of the zoom lens has alwa...
