An internal focusing light pipe with self-collimation function and its application method

Abstract

The invention relates to an internal focusing optical tube with self-collimation function and its use method. The hollow objective lens is a hollow structure, which is arranged on the optical axis between the fixed positive lens and the focusing lens, and the focusing lens can The axis moves in the hollow structure including the hollow objective lens to complete the task of focusing; the cross reticle is on the focal plane of the hollow objective lens. The optical system string shaft of the present invention generally uses a general-purpose internal focusing light pipe, and the purpose of the optical system through the shaft is realized by repeatedly adjusting the focal length, and the new internal focusing light pipe is based on the general-purpose internal focusing light pipe It has been improved by integrating the inner focusing light pipe and the self-collimation light pipe together to achieve self-collimation while focusing, which can effectively eliminate the self-collimation image generated by the inner focusing light pipe when it passes through the axis. The error improves the accuracy and work efficiency of the shaft. This tool has a wide range of application value in the field of optical-mechanical adjustment.

Description

technical field [0001] The invention belongs to the technical field of optical system installation and adjustment, and relates to an internal focusing light pipe with self-collimation function and its use method, in particular to a multi-piece lens optical penetrating shaft with optical path refraction in the optical system. Inner focusing light pipe with auto-collimation function and usage method. Background technique [0002] With the continuous development of optoelectronic technology, the distance required to observe the target is getting farther and farther, the overall resolution of the optical system is getting higher and higher, and the multi-lens optical system has become the norm. In order to ensure the imaging quality of the entire system, it is necessary to ensure the consistency of the optical axes of each lens group, which also puts forward higher requirements for the threading tool and the threading scheme. [0003] Now the commonly used optical system thread...
