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.

Among the imported PAs, PA modified plastics accounted for 3,700 tons, the highest proportion. According to market analysts, PA copolymers mainly include glass-reinforced PA6 and glass-reinforced PA66, which are popular in the Russian market. As another major class of PA derivatives, the proportion of unfilled PA6 imports accounts for 20% to 22% of total PA imports. From January to June this year, Russia imported 1300 tons of this material. Jiuzhi Plastics Network
