SAN DIEGO--(BUSINESS WIRE)--Filmetrics has announced an online reflectance calculator for simulation of reflectance spectra. It calculates the optical response of thin-film structures consisting of up to 20 individual layers in the spectral range between 200 nm and 2000 nm. It can be used to design functional materials such as anti-reflection and high-reflectance coatings and optical filters. With already well over 1,500 visitors per month, the calculator enjoys great popularity.
The Filmetrics calculator uses the complex-matrix form of the Fresnel equations, which is also used by the calculating engine of all Filmetrics thin-film analyzers. For the film materials, the user can either enter a specific refractive index value or select from 60 common material files from Filmetrics’ vast database, many of which are also available for download.
