Thin-Film Optical Coating Calculator — Frequently Asked Questions
Q1 How does an anti-reflective coating work? ▾
Light reflecting from the top surface and bottom surface of a quarter-wave thick film undergo destructive interference because they are 180° out of phase.
Q2 What is the ideal refractive index for a single-layer AR coating? ▾
n_film = √(n_incident × n_substrate). For air (1.0) and glass (1.52), ideal n_film = 1.23.
