Debris shields are used to prevent damage to critical high precision optical components in beam delivery systems caused by dust, shrapnel and fragments originating from the target in high energy laser experiments. Optical Surfaces debris shields offer a cost-effective solution that extend the operational life of expensive high power refractive and reflective optics.
Placed in the beam path, usually after a focusing lens or mirror, to physically block contaminants from reaching sensitive internal optics, debris shields are considered a sacrificial component within a high-power laser beam focusing system.
Working with a range of glasses including BK-7 and fused silica, which offer good homogeneity and transmission from the UV to the Near-IR, Optical Surfaces Ltd. is today a leading supplier of large diameter debris shields for high-power lasers.
Manufacturing large, high quality debris shields must satisfy the dual demands of producing a precision wavefront on a flexible window with a high diameter to thickness ratio. Benefiting from a stable manufacturing environment and proprietary production techniques - the skilled and experienced craftsmen at Optical Surfaces Ltd can economically produce debris shields of diameter (up to 600 mm) and thickness (5-30 mm) with typical wavefront error of lambda/10 and surface finish of 40/20 -10/5.
