Debris shields reduce operating costs of high power laser facilities

Optical Surfaces Ltd (www.optisurf.com), specialists in large and high precision optics, have considerable expertise in the manufacture and supply of debris shields to protect the target-facing optics of large high-power laser facilities.

As large laser facilities increase in beam energy and target size, the likelihood of producing shrapnel and debris that may impact and degrade target-facing optics lifetimes also increases. The use of debris shields to protect these high precision final reflective or refractive focusing optics is a well-established technique of cost effectively extending their lifetime.

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 debris shields for high-power lasers.

Manufacturing large, high quality debris shields combines 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 Optical Surfaces Ltd.'s skilled and experienced craftsmen are able to economically produce debris shields of diameter (75 - 400mm) and thickness (2-15mm) with typical wavefront error of lambda/10 and surface finish of 40/20 -10/5.

Optical Surfaces ISO 9001-2000 approved manufacturing facility provides the flexible resources to supply from single specialist requirements to OEM quantities. All high-power laser debris shields are provided with a complete quality test assurance report.
