[0002] The glass free-form spherical optical lens shape measurement device is a professional equipment for high-precision shape measurement of free-form optical lenses. Equipped with high-precision sensors and intelligent software, the device realizes automated measurement and data analysis. It can accurately detect the micro-contour parameters, horizontal axis angle, optical axis position parameters, etc. of the lens with a measurement accuracy of up to nm level. The device is not only suitable for spherical and aspherical lenses, but also can cope with customized measurement of complex curved lenses, providing important quality assurance for optical component manufacturing.
