Abstract
Normal-incidence multicycle broadband AR coatings on glass with low residual over the wavelength region 400 nm to 800 nm are theoretically discussed. Using the method of effective interfaces and the concept of equivalent index layers a 4-layer design sub(AHBL)air is expanded into the designs sub [AHC2LCBL]air and sub[AH(C2LC)2BL]air were A, B, C, H, and L are quarter-wave layers with refractive indices nH = 1.38, nL = 2.35, and nL
