The optical coating includes an anti-reflective coating and a scratch-resistant coating forming an anti-reflective surface. The article exhibits a maximum hardness of 12 GPa or greater, as measured on the anti-reflective surface by a a Berkovich Indenter Hardness Test along an indentation depth of about 100 nm or greater. The articles of some embodiments exhibit a single side average light reflectance measured at the anti-reflective surface of about 8% or less over an optical wavelength regime in the range from about 400 nm to about 800 nm and a reference point color shift in transmittance or reflectance of less than about 2. In some embodiments, the article exhibits an angular color shift of about 5 or less at all angles from normal incidence to an incident illumination angle that is 20 degrees or greater.

摘要： A scratch resistant alkali aluminoborosilicate glass. The glass is chemically strengthened and has a surface layer that is rich in silica with respect to the remainder of the glass article. The chemically strengthened glass is then treated with an aqueous solution of a mineral acid other than hydrofluoric acid, such as, for example, HC1, HNO
3 , H
2 SO
4 , or the like, to selective leach elements from the glass and leave behind a silica-rich surface layer. The silica-rich surface layer improves the Knoop scratch threshold of the ion exchanged glass compared to ion exchanged glass that are not treated with the acid solution as well as the post-scratch retained strength of the glass.
