Preparation and Performance Investigation of Broadband Antireflection Coatings in the Visible and Near-Infrared Spectral Regions

A seven-layer broadband antireflection coating consisting of Al2O3, TiO2, SiO2, and MgF2 was designed and deposited on both sides of K9 glass for the 400–1100 nm range. The deposition parameters for TiO2 and SiO2 single layers were optimized, and the measured optical constants were used in TFCalc to refine the multilay...
