Estimation of the minimum achievable reflectance of broadband anti-reflection coatings

BBAR schematic 3

Fig. 1. Schematic representation of AR performance in a broadband spectral range.

Here you can estimate minimum achievable reflectance of broadband AR coatings (ratio of right and left boundaries of the operating AR range is larger than 2; s-polarization case). Please input parameters required for calculations.

Boundaries of the AR wavelength range: λl  = nm   λu  = nm

High and low refractive indices: nH  =   nL  = Substrate refractive index: ns  =
