Optical Lens AG/AR/AF process applications
We offer complete optical lens production processes, including injection molding, strengthening, coating, AG, AR, and AF, as well as printing and CNC processing.

Surface-strengthening nanocoating treatment increases surface wear and scratch resistance. AR coating increases lens transmittance and reduces reflectivity. AF(S) water-repellent treatment reduces dust and fingerprints. Applications include glass, plastic, and other highly transparent materials.

AR PRODUCTION INTRODUCE
  • AR (anti-reflection coating) is a coating that works based on the principle of thin-film interference. This coating is a uniformly thick layer of transparent dielectric applied to the lens surface. This creates destructive interference between the upper and lower surfaces for reflected light of a specific color, reducing reflections and increasing the intensity of transmitted light for clearer images.
  • We generally think of transparent, colorless glass as 100% transmissive. However, if you look closely at certain angles, you'll see reflections. This is due to surface reflection. Normal glass reflects light from both surfaces, and the glass itself (silicon, sodium, calcium, etc.) also absorbs light. Therefore, strictly speaking, transparent glass is not 100% transmissive. After deducting the reflections and absorption from both surfaces (absorption varies by 0.1% to 2% depending on the glass material and thickness, with 0.5% used as an example), the transmissivity is approximately 91% to 92%.
AR Process Advantages
● Depending on the material's penetration characteristics, the penetration rate needs to be increased based on the measured penetration rate of the material.
● Coating can only increase the transmittance by 2.5%~3%, effectively reducing reflected light.
  • Description of the single-sided AR AR process

    • Used in camera lenses and monitors • Applied to PC and composite materials︰ - The transmittance before coating is about 88~91%.
    - After coating, the transmittance can be increased to 91~94%     • Applied to PMMA material: - The transmittance before coating is about 90~92%
    - After coating, the transmittance can be increased to 93~95%     • The reflection color can be divided into (blue film, blue-purple film, red-purple film, yellow-green film, etc.) • Increase 2.5~3% transmittance and reduce reflection.

  • Description of the double-sided AR AR process

    • Used in camera lenses and monitors • Due to PC and composite board materials: -The transmittance is about 88~91% before coating
    -After coating, the transmittance can be increased to 94~97%     • For PMMA material: -Before coating, the transmittance is about 90~92%
    -After coating, the transmittance can be increased to 97~98%.     • The reflection color can be divided into (blue film, blue-purple film, red-purple film, yellow-green film, etc.) • Increase 5~6% transmittance and reduce reflection.
