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. has earned a reputation as a leading supplier of large, high precision laser windows.
Benefiting from a stable manufacturing environment and proprietary production techniques skilled craftsmen are able to routinely produce high-power laser windows up to 600mm in diameter with typical wavefront error of lambda/10 and surface finish of 40/20 to 10/5.
To optimise the performance of rapid-pulsed (femtosecond) high-power lasers - Optical Surfaces Ltd is able to supply the latest dielectric coatings on windows to provide minimum pulse distortion, maximum usable bandwidth and durability.
In applications where there is significant risk of mobile material as a result of high-power laser ablation - Optical Surfaces Ltd also has considerable experience of producing large ultra flexible windows (debris shields) to protect the final high precision lens that focuses laser energy onto the targets. Manufacturing debris shields combines the dual demands of producing a precision wavefront (typically lambda/5 to lambda/10) on a flexible window with a high diameter to thickness ratio (e.g. 372mm diameter and 10mm thickness).
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 windows are provided with a complete quality test assurance report.
