Large Diameter Aspheric Lens

High Throughput Aspheric Lenses

Optical Surfaces Ltd. is a leading manufacturer of high quality aspheric lenses for a wide array of demanding optical applications that involve beam focusing, collimation, expansion or wavefront correction. Aspheric lenses provide a cost effective way of reducing the number of optical elements in a system. A correctly formed aspheric lens surface may cancel or control spherical aberration. As a result more energy can be concentrated into a smaller area. Aspheric ...
