Q: How are the surfaces of aspheric lenses defined, and what are the manufacturing capabilities of Avantier?
A: Aspheric lenses are defined by their surface profile, either by sag or orthogonal coefficients Qbfs and Qcon. Avantier employs state-of-the-art grinding and polishing equipment, including computer-controlled precision polishing devices and magneto-rheological finishing (MRF) technology, ensuring optimized surface quality. Manufacturing capabilities include diameters ranging from 5 to 200mm, precise tolerances, and various surface quality options.
