Abstract:
Methods and apparatus for measuring a thickness of a coating on an moving object are provided. Light is directed toward the object at a predetermined location on the object such that a portion of the light interacts with the object. A 1D and/or 2D maximum intensities for at least one wavelength channel is captured that is produced by the portion of the light interacting with the object. A measured average intensity of the wavelength channel and/or intensities and their arithmetic derivatives of multi wavelength channel geometries is converted into 1D (averaged) and/or 2D thickness values. Based on these values an acceptability of the coating is evaluated and thickness calculated.

Abstract:
A nitrogen-containing TCO (Transparent Conductive Oxide) cap composition or layer that may be used as a capping over a TCO layer (such as doped zinc oxide) to provide enhanced thermal, chemical and scratch resistant properties. It may also be used to improve the surface smoothness of the resultant stack. The nitrogen-containing TCO cap composition or layer may be deposited onto a TCO layer, which is deposited on a transparent substrate such as glass using chemical vapor deposition methods. The nitrogen-containing TCO cap compositions or layers are comprised of at least 2 different metal elements with one of them being a Group liA element (i.e., B, Al, Ga, In, Tl, Uut.) along with oxygen and nitrogen.
