Spectral Thin Film Reflectance Calculator for Thin-Film Stacks
This calculator is used to calculate the reflectance spectrum caused by interference phenomena between thin films. Based on the same calculation engine as KLA thin film measurement systems, it uses the complex-matrix form of Fresnel equations for precise calculation.
Uses rigorous electromagnetic theory to calculate the optical properties of multi-layer thin film systems through the transfer matrix method. Considers thin film interference, dispersion effects, and polarization characteristics.

Material refractive index data comes from the KLA online database. Please note that not all materials have a complete data range of 200-2000 nm. For missing data, the system will use interpolation methods for estimation.
Future versions will support more advanced features including: graded layers, graded interfaces, roughness, superlattices, custom material addition, saving thin-film stack structures, etc.
This calculator uses the same calculation engine as KLA thin film measurement systems, based on the rigorous complex-matrix form of Fresnel equations, providing high-precision optical property calculations.
