Why Our Coating Works
Principle of Multilayer Thin Film Coating (Quarter-Wave Stack)
Thin-film coatings are designed using alternating high-index and low-index layers, each with a quarter-wave optical thickness.
This multilayer structure creates constructive and destructive interference, precisely controlling reflection and transmission across the spectrum.
