Germanium Infrared Ge aspheric lens

In the modern optical system,the advantages of aspherical lens such as improving the system imaging quality,simplified the structural complex degree,increasing the system reliability,etc. allowing the aspherical lens broadly used in the different kinds of optical system.

Precision Optical aspheric Lens are designed to focus light while eliminating spherical aberration from divergent light sources in applications including focusing the output of a laser diode. Aspherical lens can increase the numerical aperture of a lens while minimizing system aberrations. Aspherical lens may also reduce the number of elements needed in a multi-element system. Convex Aspheric lenses can reduce overall system weight while providing advantages such as increasing throughput or simplifying assembly.

The application of aspherical lens will more and more comprehensive.Optical aspherical lens has already application in various high technology project and products.
