Research Team Discovers How to Create and Control Structural Color
Researchers have shown how a clear surface covered in transparent droplets and lit with a single white-light lamp can produce bright, iridescent colors if each droplet is precisely the same size. “Structural color” is formed based on the size and curvature of the droplets, along with the droplet’s total internal reflection.

Thermally Painted Metasurfaces Yield Perfect Light Absorbers for Sensing, Solar, Stealth Technologies
Thermally Painted Metasurfaces Yield Perfect Light Absorbers for Sensing, Solar, Stealth Technologies
A 3000-year-old metallurgy technique of heating metal to create vibrant colors creates a nanostructured surface that can act as a perfect light absorber, researchers from Case Western Reserve University have found. The team applied its findings to create a nickel thin-film that perfectly absorbs red light.

A Bird’s-Eye View of AR Coatings, from Concept Through Production
A Bird’s-Eye View of AR Coatings, from Concept Through Production
Tue, Mar 12, 2019 1:00 PM - 2:00 PM EDT
This webinar will present the concepts and design principles of antireflection (AR) coatings, the most common optical thin-film coating produced today and for more than 80 years. It will discuss the equipment used in AR coating production and the process aspects of AR coatings. Many other types of coatings have evolved from these same principles, equipment, and processes, and these will be touched on briefly, but the focus of the webinar will be on AR coatings. The webinar is sponsored by North American Coating Laboratories, Satisloh GmbH, Bühler Leybold Optics, and Newport Thin Film Laboratory, Inc.
