Abstract
Optical coatings generally consist of thin films made up of single or multiple layers of either metallic or dielectric materials. When properly designed and fabricated, these coatings can substantially modify the reflection and transmission properties of an optical component. Almost all lenses have AR coatings to maximize transmission factor and minimize ghost images factor. Even we talk about glasses or complex optical systems, AR coatings of one or many layers, depending on what is intended to gain. When it comes about mirrors, AR eliminated old technologies based on complex matrix and super polished, raising reflection factor light weight and low cost. The paper is focused on a guide for selecting optical materials and proper optical coating types depending on the wavelength range and the applications requirements. The software permits selection of optical materials and optical coatings for certain application considering spectral domain, spectral characteristics such as transmittance/reflectance, material, coating technology, number of layers and incidence angle. The selection guide was developed in Matlab environment. The program is a useful tool for knowledge of coating types and selection of proper optical coating for a specific application and for a group of convenient substrates. Selecting the right optical glass for a particular application can significantly impact cost, durability, and performance. In a future development of the interface, some features will be added, such as adding materials catalogues and matching criteria for better combinations between substrates and coatings.
