Description

Technical Field

[0001] This utility model relates to the field of lens scratch detection technology, specifically a portable lens scratch detector. Background Technology

[0002] With the rapid development of optical technology, lenses (such as eyeglass lenses, camera lenses, and optical instrument lenses) are increasingly widely used in daily life and industrial production. The surface quality of lenses, especially the presence and extent of scratches, directly affects optical performance, image clarity, and equipment lifespan. Therefore, lens scratch detection has become a key aspect of quality control and maintenance of optical products.

[0003] Currently, traditional lens scratch detection technology mainly relies on laboratory testing equipment. This equipment utilizes advanced optics and image processing technology to perform high-resolution scanning and analysis of lens surfaces, accurately detecting scratches. While these devices are powerful, they are complex in structure, bulky, and require fixed installation. When conducting on-site lens testing, the lens angle cannot be adjusted, and they are inconvenient to carry, failing to meet the needs of on-site testing. Therefore, those skilled in the art have provided a portable lens scratch detector to solve the problems mentioned in the background section. Utility Model Content
