Optical Surfaces aspheric lenses have use in high-power laser focusing applications

Aspheric lenses up to 600 mm diameter feature a surface finish of 20/10 scratch/dig, 1 nm rms surface roughness, and low f-numbers for applications including high-power laser focusing, lidar, and laser launch telescopes. The ISO 9001-2008 approved manufacturing workshops and test facilities are deep underground in a series of tunnels excavated in solid chalk, where temperature remains constant and vibration is nearly non-existent.
