OVERVIEW
Aspheric lenses are 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 lenses are best suited for low f-number, high throughput applications.
Optical Surfaces has made a speciality of producing high quality aspheric lenses for many end users particularly in the high-energy laser research field.
