Toric Lenses

Toric Lenses

A toric surface deems as an arc rotates around an axis of another axis, it’s mostly used to replace several optical lenses to simplify the structure of the equipment and improve image quality. Unlike smooth reflector and single spherical reflector that have some problems like anamorphose by reflection, the toric lens will assist in reducing the number of optical lenses needed.

Toric Lenses Process Capability

Boxin is equipped with 30 sets Toric Lens CNC Grinding and Polishing machines that imported from EU. We introduced Interferometer for accuracy inspection. For measuring data of special product we equipped Diffraction Lenses. We can process various materials. The process range from 10mm-300mm, and annual output is 150,000 pieces.
