Problems solved by technology

[0003] Optical-grade plastic lenses generally use optical-grade methyl methacrylate, polycarbonate and other materials. The advantages of optical-grade plastics are: small mass, easy to form complex curved surfaces, low cost, and easy to achieve large-scale production; the disadvantages are: high temperature resistance and The aging resistance is not strong, for example, the temperature resistance of methyl methacrylate does not exceed 80°C (heat distortion temperature 92°C), and the temperature resistance of polycarbonate does not exceed 120°C (heat distortion temperature 135°C).

Description

technical field [0001] The invention relates to lens materials, in particular to a polyamide resin lens material. Background technique [0002] An optical lens is an optical component made of a transparent substance. The selection of optical lens materials is restricted by factors such as molding difficulty, light transmittance, cost and stability, and glass and transparent plastics are generally selected. [0003] Optical-grade plastic lenses generally use optical-grade methyl methacrylate, polycarbonate and other materials. The advantages of optical-grade plastics are: small mass, easy to form complex curved surfaces, low cost, and easy to achieve large-scale production; the disadvantages are: high temperature resistance and The aging resistance is not strong, for example, the temperature resistance of methyl methacrylate does not exceed 80°C (heat distortion temperature 92°C), and the temperature resistance of polycarbonate does not exceed 120°C (heat distortion temperat...
