Abstract
This disclosure is directed to an improved process for making glass articles having optical coating and easy-to clean coating thereon, an apparatus for the process and a product made using the process. In particular, the disclosure is directed to a process in which the application of the optical coating and the easy-to-clean coating can be sequentially applied using a single apparatus. Using the combination of the coating apparatus and the substrate carrier described herein results in a glass article having both optical and easy-to-clean coating that have improved scratch resistance durability and optical performance, and in addition the resulting articles are “shadow free.”
