Abstract: A transparent article is described herein that includes: a glass-ceramic substrate comprising first and second primary surfaces opposing one another and a crystallinity of at least 40% by weight; and an optical film structure disposed on the first primary surface. The optical film structure comprises a plurality of alternating high refractive index (RI) and low RI layers and a scratch-resistant layer. The article also exhibits an average photopic transmittance of greater than 80% and a maximum hardness of greater than 10 GPa, as measured by a Berkovich Hardness Test over an indentation depth range from about 100 nm to about 500 nm. The glass-ceramic substrate comprises an elastic modulus of greater than 85 GPa and a fracture toughness of greater than 0.8 MPa·√m. Further, the optical film structure exhibits a residual compressive stress of ≥ 700 MPa and an elastic modulus of ≥140 GPa.

Abstract: An optical film structure that includes: an optical film comprising a physical thickness from about 50 nm to about 3000 nm, and a silicon-containing nitride or a silicon-containing oxynitride. The optical film exhibits a maximum hardness of greater than 18 GPa, as measured by a Berkovich Indenter Hardness Test over an indentation depth range from about 100 nm to about 500 nm on a hardness stack comprising a test optical film with a physical thickness of about 2 microns disposed on an inorganic oxide test substrate, the test optical film having the same composition as the optical film. Further, the optical film exhibits an optical extinction coefficient (k) of less than 1×10−2 at a wavelength of 400 nm and a refractive index (n) of greater than 1.8 at a wavelength of 550 nm.

Abstract: An optical element including an optically transparent lens which defines a curved surface having a steepness given by an R/# of from about 0.5 to about 1.0. A film is positioned on the curved surface. The film includes an index layer. A composite layer is positioned on the curved surface having a refractive index greater than the index layer. The composite layer includes HfO2 and Al2O3. The composite layer has a mole fraction X of HfO2, wherein X is from about 0.05 to about 0.95 and a mole fraction of Al2O3 in the composite layer is 1−X.
