Abstract
Stacks of quarter wave and non-quarter wave multilayer coatings are used for alter the optical properties of a substrate, like increasing or decreasing reflection. Anti-reflective coatings and highly-reflective coatings are two examples that are widely used. Thin film technology is also used to construct hot and cold Mirrors (Dichroic) High pass Filters and Low Pass filters, Beam Splitters, Interference Filters, Neutral Density Filters, Polarizing Beam Splitters, Transparent Conducting Coatings. In this study dielectric high reflective and antireflective mirrors are formed with reflectivity above 99% and transmission in antireflective mirrors also greater than 99% at 1064 nm in infra-red region with ZrO₂ and SiO₂ materials. Reflection and transmission is measured by spectrophotometer.
