Abstract

Antireflection coatings (ARC) have been modeled and prepared experimentally for optical and electro-optical applications in the visible spectrum (0.4--0.7 \mu m) to reduce reflections from the surface of glass. Reflection of BK7 bare glass substrate varies from 3.5 to 6.0% over the desired spectrum. This value is reduced reasonably by integrating multilayer thin films, based on dielectric materials, behaving as ARC. Three different three-layer configurations are deposited on glass substrate. The reflection profiles of theoretical and experimental curves are compared and analyzed to demonstrate the use of these multilayered structures. The physical parameters and deposition conditions of the three configurations are optimized before multilayer deposition. The prepared samples have shown very good results.
