Aspherical lenses

Aspherical lenses have its advantages in a range of applications where eliminated spherical aberration or (and) single element design is required. Glitter offers CNC precision-polished aspherical lenses. 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
