Overview
Freeform surface 3D surface detector $r $n Freeform surface optical components are applied in cutting-edge fields such as intelligent vehicle displays, AR displays, mobile phone lenses, laser displays, lighting, photolithography, etc. The free-form surface 3D surface detector can non-contact measure the 3D surface data of optical mirror components, conduct 3D contour analysis and 3D error comparison, and generate measurement reports containing multiple surface error indicators. From product development to production process and quality control, this independent system can be used for front-end R&D design process, intelligent production process, and back-end quality inspection process of optical design, processing, and testing.
