For a wide array of demanding optical applications Optical Surfaces has manufactured aspheric lenses, which involve beam focusing, collimation, expansion or wave front 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 lenses are best suited for low f-number, high throughput applications.
Drawing on its team Optical Surfaces offers fabrication of high performance aspheric lenses up to 600mm diameter in a range of high-quality optical glasses with low f-number to optimise light gathering and focusing performance.
To meet the demands of high-power laser focusing, LIDAR and laser launch telescopes Optical Surfaces is routinely able to manufacture aspheric lenses with surface finish of 10/5 scratch/dig, surface roughness of 1nm rms and ultra-smooth slope errors.
A range of high-power laser coatings are also available to maintain high transmission and enable the aspheric lenses to operate at the ultra-high energy thresholds demanded by the Terawatt lasers used to investigate fundamental plasma physics.
