  • ACETRON Low Refractive Index Material

    This is a type of coating-type low-refractive-index material that effectively reduces optical refractive index. This material can form high-transmittance, high-reliability low-refractive-index thin films. It enhances the light reception efficiency of optical sensors, reduces ghosting and glare caused by lens surface reflections, and addresses optical issues in various displays such as CIS, CCD, OLED, micro LED, LCD, etc.

  • Features

    Low-refractive-index thin film material with controllable refractive index

    High transparency coating material

    Thermosetting material

    Suitable for applications requiring optical design (such as light reflection suppression, light extraction, etc.)
