Design front and back coatings, calculate reflectance and transmittance, and download your design. Calculations run in your browser.
Calculation settings
Out-of-range material data: If a calculation wavelength is below or above a material's tabulated range, the calculator holds that material's nearest endpoint n and k values constant. This is not a physical extrapolation and results outside the source data range should be treated with additional caution.
Custom material: enter a name and constant n and k, then add it to the material menus.
