Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing, in particular to an optical lens mold with uniform heat dissipation. Background Art

[0002] The main raw material of lenses is optical glass, which has relatively superior optical properties, good light transmittance and mechanochemical properties, a constant refractive index, and stable physical and chemical properties; secondly, glass lenses have a higher refractive index, and the highest refractive index commonly used for lenses is 1.9. Finally, glass lenses have a high surface hardness and are more wear-resistant. However, due to material reasons, glass lenses are heavy, which affects their wearing comfort to a certain extent. In addition, glass lenses are fragile, especially with the improvement of production technology and process of resin lenses. In recent years, the use of glass lenses has become less and less. Optical glass is mixed with high-purity silicon, boron and other oxides according to a specific formula, melted at high temperature, stirred evenly with ultrasound, and bubbles removed. After cooling, the qualified glass blocks are heated and forged to form optical lens blanks.
