Optical Surfaces’ debris shields for target-facing optics protection are being offered in any shape and thickness.
The use of debris shields to protect expensive reflective or refractive focusing high power optics is an established technique for extending their lifetime. Working with a range of glasses including BK-7 and fused silica, which provide transmission from the ultraviolet to the near-infrared, Optical Surfaces is able to supply customer specified debris shields in many shapes and thicknesses. Debris shields up to 600mm in diameter with a typical wavefront error of lambda/10 and surface finish of 40/20-10/5 cam be produced.
