Kenley, UK, January 30, 2004. Working with materials including BK-7 glass and silica, Optical Surfaces can supply high-precision large window optics up to 600mm in diameter. Using proprietary production technologies and the knowledge and skill of master optics craftsmen Optical Surfaces has become a leading supplier of larger diameter windows for high-power laser, astronomy and aeronautical applications.

Where high-power laser ablation has mobilized material, Optisurf transparent debris shields are widely used to protect the final lens that focuses laser energy onto the targets. Manufacturing debris shields combines the dual demands of producing a precision wave-front (typically lambda/5 to lambda/10) on a flexible window with a high diameter-to-thickness ratio. A recently supplied debris shield was of typical specifications, 372mm diameter and 10mm thick, providing an ultra-flexible substrate.

Optical Surfaces can also produce large-diameter windows for telescope closures and aerial surveillance and reconnaissance applications. Production approved to ISO 9001-2000 and with all optics interferometer tested before shipping ensures the quality of large flexible window optics from Optical Surfaces.
