Large Aspheric Lenses Available From Optical Surfaces

Optical Surfaces : 30 September, 2010  (New Product)
Optics specialist can provide custom aspheric lenses of up to 600mm diameter for demanding applications
Large Aspheric Lenses Available From Optical Surfaces
Using proprietary manufacturing techniques, Optical Surfaces has earned an international reputation for producing diffraction-limited aspheric lenses for the most demanding applications.

Optical Surfaces is renowned for producing aspheric lenses 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 able to manufacture aspheric lenses up to 600mm in diameter with surface finish of 20/10 scratch/dig, surface roughness of 1nm RMS and ultra-smooth slope errors. A range of durable coatings are available for aspheric lenses to maintain high transmission and to enable operation at the ultra-high energy thresholds demanded by the latest generation of high power lasers.

An aspheric surface profile is often used to eliminate spherical aberration and reduce other aberrations associated with simple lenses. A single aspheric lens can often provide a smaller, lighter, less-expensive alternative to a traditional complex multi-lens system.
