Auxiliary adjustment device for optical lenses

Abstract

The invention relates to an auxiliary adjustment device for optical lenses and belongs to the field of optical systems. The auxiliary adjustment device for optical lenses solves the technical problems that as the center deviation and the lens interval of optical lenses are detected separately in the prior art, the measurement accuracy is low and cost is high. The auxiliary adjustment device for optical lenses comprises a center deviation measurement module, a lens interval measurement module, a reflector, a linear guide rail, a precision turn table, a mechanical adjustment platform and a main control computer, wherein the center deviation measurement module comprises an optical lighting module, a beam splitter, a collimating lens set, a focus lens set, a photoelectric detector and a linear displacement sensor. The auxiliary adjustment device for optical lenses integrates the center deviation measurement function and the lens interval measurement function for optical lenses, not only is the manufacturing cost low, but also it is ensured that the same reference axis is adopted in the adjustment process of optical lenses, the adjustment accuracy of optical lenses can be improved, the adjustment process of optical lenses is simplified, and consequently the adjustment efficiency of optical lenses is improved.

Description

technical field [0001] The invention relates to an auxiliary optical lens assembly and adjustment device, which belongs to the field of optical systems. Background technique [0002] Optical systems have been widely used in various fields such as national defense and military, industrial production, and daily life. In many applications, the performance requirements of optical systems are getting higher and higher. In order to achieve high performance, the optical lens is required to have high adjustment accuracy, and the adjustment process is strictly controllable to ensure the consistency of optical system performance. During the assembly and adjustment of optical lenses, the eccentricity of optical lenses and the air space between optical lenses must be accurately measured. [0003] In the prior art, there are devices for measuring the center deviation and lens spacing of optical lenses, but there is no auxiliary optical lens assembly equipment that can measure the center...
