Optical Window Specifications
Precision Optical has capacity to handle the most demanding requirements for optical flats, mirrors, and windows. From miniature Risley wedges to high-powered laser line mirrors to large interferometer flats, our experienced polishing technicians produce optical components with superior flatness, transmitted wavefront, parallelism and mechanical dimensions, with minimal cosmetic surface defects.
