High Quality Ar Coating Dlc Coating Infrared Germanium Ge Lens

An aspheric lens is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.

The asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter, and sometimes cheaper than the multi-lens design. Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations. 

We provide all kinds of customized optical lens which according to your drawings, sample products or detailed requirements. Any inquiry please feel free to contact us, thanks!
