Aspherical lenses

Molded glass aspheres can be manufactured with more than 15 types of glass materials. Outer diameter of the lenses ranges from 1.8 to 60 mm, and surface roughness can be as low as 10 mm. Molds that can produce 100,000 lens elements eliminate most lot-to-lot variations. Molded aspheres are available for digital camera lenses, lasers, and fiberoptics.
