Empirical expression for the minimum residual reflectance of normal- and oblique-incidence antireflection coatings

Appl Opt. 2008 Jun 10;47(17):3109-13. doi: 10.1364/ao.47.003109.

Abstract

A new empirical expression for estimating minimum achievable residual reflectance of antireflection (AR) coatings is presented. The expression gives an accurate approximation of the minimum residual reflectance for normal- and oblique-incidence AR coatings in the visible and infrared spectral ranges.
