Hemispherical Aspherical Lens

Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. Aspheric lenses may also reduce the number of elements needed in a multi-element system. Aspheric lenses can reduce overall system weight while providing advantages such as increasing throughput or simplifying assembly.

Convex Aspheric elements are used to reduce aberrations, aspheric lens is ideal for light collection, projection, illumination, detection, and condensing applications.

China Star Optics has strong and comprehensive technical capability, manufactured various aspherical products,including infrared material ZnSe,Ge,Si,ZnS etc.has already application in various high technology project and products.
