Aspheric Lens is used to eliminate spherical aberration. It utilizes a single element design which helps minimize the number of lenses found in multi-lens optical assemblies. Said another way, unlike conventional lenses with a spherical front surface, aspheric lenses have a more complex front surface that gradually changes in curvature from the center of the lens out of the edge of the lens. Rising EO' aspheric lens is available molded and CNC-polished. Precision molded technology ensure the consistency of the aspherical lens and also low cost. Based on the technology, the lens could achieve a good surface accuracy and quality, Whilet the prototypes cost is high. The molded lenses are suitable for a variety of lighting and detection applications, but not recommended for high power laser systems. Compared to the molded aspheric lens counterparts, CNC-polished aspheres are available in larger sizes, provide better surface quality, and maintain the M squared values of the input beam better.
