aspheric lenses

Benefiting from a uniquely stable manufacturing environment – Optical Surfaces Ltd. is able to produce diffraction-limited aspheric lenses up to 600mm in diameter for the most demanding applications.

With over 40 years experience, Optical Surfaces are acknowledged as a leader in producing high quality aspheric optical systems and instrumentation for a wide range of research and test applications.

Optical Surfaces produces 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 with surface finish of 20/10 scratch/dig, surface roughness of 1nm rms and ultra-smooth slope errors.

A range of high-power laser coatings is available to maintain high transmission and enable Optical Surfaces’ aspheric lenses to operate at the ultra-high energy thresholds demanded by the Terawatt lasers used to investigate fundamental plasma physics.

A rolling program for the calibration of test optics to national standards, where possible, and production approval to ISO 9001-2008 ensures that the quality of aspheric lenses from Optical Surfaces is second to none.
