Debris Shields

KENLEY, England, April 11, 2012 — 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 are available with up to a 600-mm diameter, typical wavefront error of λ/10 and surface finish of 40-20 to 10-5.
