Description
Technical Field
[0001] This utility model relates to the field of optical lens testing technology, and in particular to an optical lens testing structure. Background Technology
[0002] As a core component of optical systems, optical lenses directly impact image quality and usability. The precision and flexibility of the testing structure are crucial in the production and testing of optical lenses. Traditional testing equipment has limitations in lens clamping, positioning, and test range adjustment, making it difficult to meet the testing needs of optical lenses of different sizes and shapes. With the rapid development of optical technology, developing an optical lens testing structure that can adapt to various lenses and achieve precise adjustment and efficient testing is of great significance for improving production efficiency and product quality.
[0003] Existing optical lens testing structures typically employ fixed clamping devices and manual adjustment mechanisms. The lens is held in place by a fixed clamp, and testing is performed by manually adjusting the position of the light source or imaging device. While this structure meets basic testing requirements, it suffers from shortcomings in clamping stability, adjustment accuracy, and applicability, especially when handling lenses of different sizes or special shapes, making it difficult to achieve rapid and accurate testing.
[0004] However, existing clamping devices cannot flexibly adapt to optical lenses of different sizes and shapes, resulting in low testing efficiency and complex operation. Since clamping devices are mostly fixed designs, replacement or adjustment requires disassembly and reinstallation, which not only increases operation time but may also affect testing accuracy due to unstable clamping. Furthermore, traditional clamping devices are difficult to adapt to the testing requirements of lenses with special shapes, limiting the applicability of the testing structure. Therefore, an optical lens testing structure is proposed to solve the above problems. Utility Model Content
