Super Polishing Substrate
Super Polishing, also known as Ultra-Smooth polishing of the optical surface, refers to the optical surface roughness RMS < 0.2-0.5nm (2-5Angstrom), which still high in flatness and surface quality, intergration crystal structure of the surface as well.  Due to the development of the X-ray optical system, Gyro system, High power laser, Laser Display,WDM industry,the super finishing optical components are highly demand. 

High power lasers, All-Solid-State Laser,Laser Display and Illumination, Inertial Navigation etc. 

Material Fused Silica, Zerodur, Sitall etc
