Request InfoOptical Surfaces Ltd.Debris shields from Optical Surfaces Ltd. are designed to protect target-facing optics located in high-power laser facilities. Using debris shields to protect final reflective or refractive focusing high-power optics extends their lifetime. Manufacturing high-quality debris shields requires producing a precision wavefront on a flexible window with a high diameter-to-thickness ratio. Working with glasses including BK-7 and fused silica, which offer good homogeneity and transmission from the UV to the near-IR, the company provides shields of virtually any shape and thickness. They...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra September 2023 IssueModular Beam ExpanderOptical Surfaces’ pre-aligned large diameter beam expander modules enable complex 5-degrees of freedom set-up in a matter of minutes.
