Optical element manufacturing precision and stability

High-precision optical components in these industries are widely used. In the field of space-based observations, as the core component of the optical system, optical components manufacturing precision and stability of the entire optical system imaging quality and reliability play a decisive role, requiring precision optical surface nanoscale  abrasive grinding , while the optical element also requires the elimination of all the processing may affect product safety or reducing  Diamond blade  element surface / sub-surface quality factor; the laser, the resonator mirrors requires a very smooth surface to minimize reflection losses, reduce the local thermal effects and increasing the optical damage threshold laser components;
