Coated articles with optical coatings having residual compressive stress
Last updated:
Abstract:
A coated article includes a substrate having a major surface, and an optical coating disposed on the major surface of the substrate. At least a portion of the optical coating includes a residual compressive stress of about 50 MPa or more. The coated article has strain-to-failure of about 0.5% or more as measured by a Ring-on-Ring Tensile Testing Procedure. The coated article has an average photopic transmission of about 80% or greater.
