The production of a high-quality optical component is an exacting process, requiring a high level of skill, quality equipment, and close attention to detail. Our λ/8 wave first surface mirror glass offers a superior quality compared to other first surface mirrors on the market. The λ/8 flatness is achieved by polishing float glass down to a flat surface, then coating with aluminum and the protective overcoat. Typically, other companies are only able to produce the mirrors on float glass, which is 4-6λ per inch. To the naked eye, the two mirrors look the same, however the improved quality of the λ/8 is immediately noticeable under magnification.
