Reflective Coating

Reflective coating can generally be divided into two categories: metal reflective coating and all-dielectric reflective coating. Additionally, there are metal-dielectric reflective coating that combine both, which function to enhance the reflectivity of optical surfaces.

    Dielectric Coating

    Dielectric Coating
    Dielectric coatings, composed of non-conductive layers, offer high reflectivity and durability, making them essential in optics. However, they are sensitive to incident angle and polarization, and their precise, time-consuming manufacturing process increases costs. Despite these challenges, they remain invaluable in applications like laser technology and telecommunications.

  • Anti-reflection(AR) Coating
    Anti-reflection coatings reduce first surface reflection losses, improve contrast and boost the transmission through your optical surface. The anti-reflection film consists of a single layer or multiple layers. These designs are optimized to produce destructive interference with reflected light. This design approach will allow for maximum light transmission without compromising image quality.
