Calculate reflectance due to thin-film interference by entering
your films below. Reflectance at wavelengths from 200 nm to
2000 nm may be calculated. Up to 20 films may be entered. Our
Reflectance Calculator uses the same calculation engine that our
thin-film measurement systems do, which is based on the complex-matrix
form of the Fresnel equations.
Plot the Following:
Enter the refractive index of your material at 632.8nm. The Calculator will add dispersion that approximates the average dispersion of materials with that refractive index.
