LensThe SJ5720-OPT series is a capable to measure both surface roughness and profile after once scanning. Moreover, there is a dedicated software module for measurement and analysis of large aspheric surface, so this series is an ideal measurement solution for the optical lens industry.
It can also be used for profile and roughness measurement for large curved surface, such as bearings, artificial joints, precision molds, gears, blades, etc. Consequently, it is widely used in precision machining, automobiles, bearings, machine tools, molds, precision hardware and other industries.
Professional aspheric surface measurement software can analyze all aspheric surface parameters.
There are some self-checking parameters in the software, so the correctness of the input formula can be determined by self-checking.
