The anti-reflective coating may be applied to the first major surface of the glass substrate. A substrate thickness may be measured between the first major surface and the second major surface. The glass substrate may have an aspect ratio of at least about 100:1. The coated glass article may have a reflectance of less than 2% for all wavelengths from 450 nanometers to 700 nanometers. The anti-reflective coating may include one or more layers. The cumulative layer stress of the anti-reflective coating may have an absolute value less than or equal to about 167,000 MPa nm.

  • Publication number: 20200408954
    Abstract: Embodiments of a color-neutral anti-reflective coating and articles including the same are described. In one or more embodiments, a substrate includes a first major surface and an anti-reflective coating disposed on the first major surface of the substrate and having a reflective surface opposite the first major surface. In one or more embodiments, a point on the reflective surface has a single-surface reflectance under a D65 illuminant with an angular color variation, ?E? that is less than 5, where ?E?=?{(a*?1?a*?2)2+(b*?1-b*?2)2}, and a*?1 and b*?1 are any two different viewing angles at least 5 degrees apart in a range from about 10° to about 60° relative to a normal vector of the reflective surface.

  • Patent number: 10578785
    Abstract: An optical assembly and a method for making the optical assembly. The optical assembly includes an optical element; an adhesion promoter; a blocking coating; a holder; and an adhesive configured to adhere the optical element to the holder. The blocking coating includes a light absorber that does not transmit light with wavelengths from greater than or equal to about 250 nm to less than or equal to about 400 nm; The light absorber is positioned such that light having a wavelength from greater than or equal to about 190 nm to less than or equal to about 500 nm is not incident to the adhesive. The adhesion promoter improves adhesion of the blocking coating to the optical element and reduces the likelihood of delamination during handling, operation, or clearing of the optical assembly.

  • Patent number: 10459134
    Abstract: An optical assembly and a method for making the optical assembly. The optical assembly includes an optical element; a blocking coating; a capping layer on the blocking coating; a holder; and an adhesive configured to adhere the optical element to the holder. The blocking coating includes a light absorber that does not transmit light with wavelengths from greater than or equal to about 250 nm to less than or equal to about 400 nm; The light absorber is positioned such that light having a wavelength from greater than or equal to about 190 nm to less than or equal to about 500 nm is not incident to the adhesive. The capping layer is made from a material having high transmission in the UV and enables use of aggressive cleaning treatments on the optical element significant impairment of the UV transmission of the optical element.
