ANTI-REFLECTIVE COATINGS AND METHODS FOR OPTICAL LENSES

Anti-reflective (AR) coatings and methods for applying AR coatings to substrates, such as optical lenses. The coating may include a polyurethane base layer and a fluoropolymer top layer. The base layer may protect the underlying substrate, promote adhesion between the top layer and the underlying su...

More Information
Summary:Anti-reflective (AR) coatings and methods for applying AR coatings to substrates, such as optical lenses. The coating may include a polyurethane base layer and a fluoropolymer top layer. The base layer may protect the underlying substrate, promote adhesion between the top layer and the underlying substrate, and achieve index-matching with the underlying substrate. The method may involve an inexpensive and efficient solution coating process.
