High-Refractive-Index vs Low-Refractive-Index Coating Materials: From AR/Waveguide Principles to a Formulation & Material-Selection Map (Including Product Category Tables A/B/C)
The refractive index (refractive index, n) can be understood as “how slow light travels inside a material.” The higher the n, the stronger the material’s “bending ability/optical density” for light. In coatings, tuning n most commonly serves three purposes
