Kingwin Optics has developed an advanced double surface polishing method for producing high-precision thin optical windows or substrates. This technique polishes both surfaces simultaneously, ensuring accurate control of surface flatness and enhancing surface quality to a 10/5 S/D standard. These high-precision thin windows meet the stringent criteria required for ultra-thin (0.1mm, 0.2mm) applications with high surface flatness (λ/10 or λ/4 @633nm), ideal for precision optical systems such as femtosecond lasers, which are increasingly popular.
