Product Family Description

  • High Transmission
  • Eliminate Back Reflections and Reduce Glare
  • Available in a Wide Range of Sizes

High Efficiency Anti-Reflection (HEAR) Coated Windows feature dual broadband anti-reflection coatings, reducing reflectance to ≤0.5%. Anti-reflection (AR) coatings are applied to optical surfaces to increase the system's throughput and reduce hazards caused by reflections that travel backward through the system and create ghost images. The coating virtually eliminates back reflections, offering improved readability when used in industrial or scientific displays. High Efficiency Anti-Reflection (HEAR) Coated Windows have a high transmission, making them especially suitable for various optical applications. These anti-reflective windows are available in circular and square formats, with a diverse range of sizes offered in each.
