Description

Technical Field

[0001] The invention relates to the technical field of optical element processing, and in particular to an optical element core extraction device suitable for a micro endoscope. Background Art

[0002] As optical components are widely used in more and more fields, such as medical systems, military, industrial lasers, aerospace, analytical testing, etc., the precision requirements for optical components are getting higher and higher, and optical components are also becoming more and more miniaturized. Now there are two mainstream technologies for core processing of optical components: one is traditional mechanical centering core processing, that is, by placing the centered lens between a pair of coaxial high-precision chucks with end faces precisely perpendicular to the axis, using spring pressure to achieve centering, so that the entire surface of the lens contacts the end face of the chuck. At this time, the spherical center of the two surfaces of the lens is located on the axis of the joint, so that the lens is clamped and the purpose of centering is achieved; the second is laser centering core processing, the light emitted from the laser generator passes through an adjustable focus optical system, passes through a centering lens, and a photoelectric crystal converter with an adjustable micrometer is used behind the lens to receive the light spot image, and then the light spot image is displayed on the display. By rotating the lens, the eccentricity error can be determined from the movement of the light spot on the photosensitive film.

[0003] The two existing optical component core extraction technologies have great difficulties in processing micro endoscopes. Micro endoscopes have a small outer diameter. When mechanical centering is used, the outer diameter of the required chuck is too small, and the required precision of the chuck is too high. It is too difficult for personnel to trim the chuck, and it may not be possible. And when personnel put the product between the chucks by hand, it is difficult for personnel to pick it up and put it because the product is too small. When laser centering is used, the outer diameter of the micro endoscope is too small, and the outer diameter of the required chuck is too small. The laser beam cannot pass through the chuck, and the core extraction of the micro endoscope cannot be achieved. Summary of the invention
