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  =

With OTF Studio Software, you can tackle multilayer design challenges of any complexity. It offers powerful design and analysis tools, including synthesis algorithms enhanced with machine learning elements.

For trial versions, please reach out to our distribution partners.

OTF Studio workshop is an excellent opportunity to learn more about its capabilities and gain hand-on experience.
