CASTECH offers CNC precision-polished aspherical and acylindrical lenses, with or without anti-reflection (AR) coatings. Our CNC polished aspheric lenses are iteratively ground and polished by a software supported computer-controlled processing center to provide better controlled surface quality, irregularity, and focal length deviation.

CASTECH employs rigorous verification procedures to guarantee the high performance of each of our aspheric lenses. A Form Talysurf PGI profilometer allows contact measurement in grinding process while Taylor Hobson LuphoScan 260 non-contact 3D optical surface profilometer performs ultra-precision optical surfaces form measurement in polishing process.
