摘要:
A multilayer, thin-film, broad-band, anti-reflection structure applicable to transparent substrates. The present invention makes use of the UV absorption properties of zinc oxide to provide UV rejection for wavelengths shorter than 380 nm, while providing anti-reflection properties in the visible region of the spectrum. The structure provides a reflection value less than 0.25% in the visible region of the spectrum, and blocks 99 percent of UV radiation below 380 nm.
