摘要:
An optical article includes an optical element and a low refractive index layer disposed on the optical element. The low refractive index layer having an effective refractive index of 1.3 or less and including a binder, a plurality of metal oxide particles dispersed in the binder and a plurality of interconnected voids. The low refractive index layer has a haze value of at least 30%.
