Description

technical field [0001] The invention relates to the technical field of optical lens processing, in particular to a surface preparation process of a high-precision ultra-thin and ultra-flat optical lens. Background technique [0002] Optical glass is made of high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. mixed according to a specific formula, melted in a platinum crucible at high temperature, stirred evenly with ultrasonic waves, and removed air bubbles; The temperature is lowered slowly over time to avoid internal stress in the glass block. The cooled glass blocks must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to form optical lens blanks. [0003] At present, the precision and flatness of optical lenses are still not up to high standards and need to be improved urgen...
