Kenley, UK, January 17, 2003. Optical Surfaces Ltd. has announced a new technical datasheet detailing its range of aspheric focusing lenses. For applications including LIDAR research and laser launch telescopes, where a laser beam has to be precisely projected to a far object, aspheric focusing lenses are the optical component of choice. Additionally for high-power laser focusing applications aspheric lenses find particular utility as spatial filters.
Optical Surfaces Ltd. is able to meet the most demanding design and manufacturing tolerances with a choice of standard aspheric focusing lenses up to 300mm in diameter.
Using proprietary manufacturing techniques developed from 40 years experience Optical Surfaces Ltd. is able to produce from the highest quality optical glass or silica substrates aspheric focusing lenses up to F2.5 with diffraction limited performance. For the highest precision applications Optical Surfaces Ltd. aspheric lenses can be manufactured to have ultra-smooth slope errors, surface finish of 20/10 scratch /dig and surface micro-roughness typically of the order of 1nm rms.
A range of high power laser coatings (e.g. 249nm, 527 nm, 1053 nm and 1550 nm) can be provided which both maintain high transmission and enable the aspheric lenses to operate even at the ultra-high energy thresholds demanded by the leading edge terrawatt lasers being used to investigate fundamental plasma physics.
Produced under ISO 9002 manufacturing conditions all aspheric focusing lenses from Optical Surfaces Ltd. come with full interferometric quality testing assurance.
