Breakthrough in Optical coatings: Magnetron Sputter Deposition of Amorphous Silicon–SiO2 Quantized Nanolaminates

Discover the quantum leap in optical materials with Evatec’s Principal Scientists Dr. Silvia Schwyn Thoeny and Dr. Stephan Waldner’s latest research on aSi-SiO2 Quantized Nanolaminates. Their innovative concept has unveiled a new approach of light manipulation, showcasing tunable refractive indices and bandgap energies.

The creation of a longpass optical interference filter with an edge at 720 nm marks a milestone that outperforms conventional materials. This filter features a wide blocking range, a feat unattainable by SiO2-TiO2 based filters.
