  • System for evaluating thin film coatings
    Patent number: 6128087
    Abstract: A system for evaluating the reflectance of an object (e.g., a CRT) that is coated with an anti-reflective coating material is disclosed. The quality and/or uniformity of the coating is evaluated by a reflectometer. The reflectometer is positioned relative to the object by non-contact sensors. Reflectance data gathered by the reflectometer is analyzed to determine to what extent the actual coating differs from the optimal (i.e., ideal) coating. A feedback system modifies the coating process for subsequent objects in an attempt to fine-tune the coating process and achieve optimal anti-reflective coatings.
    Type: Grant
