Aspheric Lenses
Aspheric lenses have a radius of curvature that changes with distance from the central axis, which maintains good aberration correction, improves optical quality and reduces the number of optical elements, lowering design cost. They are widely used in optical instruments, imaging and the optoelectronics industry. Single aspheric lenses are produced by grinding and polishing with computer-controlled precision polishing; a Zygo interferometer and Taylor-Hobson contourgraph test report is provided.
