Anti-Reflective Surfaces

Optical components utilizing sub-wavelength surface structures can achieve ultra-high transmissions with angle insensitivity, a broad bandwidth, and high laser induced damage thresholds.

Maximize transmission and laser damage threshold!

Join us for a 45 minute webinar presented by Edmund Optics' experts Nathan Carlie, Nick Smith, and Randall Hinton to learn about the benefits of Nano-Structured Anti-Reflective Surfaces formed by reactive ion etching (RIE) and why they are a high transmission, high laser damage threshold alternative to anti-reflective multi-layer coatings.

At the conclusion of this webinar, participants will have a strong understanding around:

  • How Nano-Structured Anti-Reflective Surfaces work
  • Their unique properties and benefits
  • Controlling structures during manufacturing to tailor performance
  • Ideal applications for this technology
  • When this technology would make sense for you
