Abstract
Calculations of reflectance as a function of wavelength have been carried out for many combinations of refractive indices, for the quarter-half-quarter wavelength construction of triple-layer anti-reflection coatings on glass at the angle of incidence 45°. The indices which provide the broadest region of very low reflectance were determined. Calculations of reflectance have been then carried out for the optimized triple-layer anti-reflection coatings for angles of incidence between 0° and 65°. Equi-reflectance contours were plotted to show the range of angles of incidence over which the reflectance is less than given values.
