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.

Technical FAQ

Configuration questions for Aspheric Lenses

What is the Aspheric Lenses made from?

Material: K9, fused silica, N-BK7. Substrate and coating decide thermal behaviour and cleaning method as much as optical performance. Confirm both before the optic enters a high-average-power or vacuum path.
