Thin Film Coating

structured wafer

NQW provides a range of optical coating services, such as Anti-Reflective, High-Reflective or protected/enhanced metal mirrors. These coating can be applied to optics up to 12″ diameter having various shapes and sizes. Prior to coating the optics can be cleaned in our semiconductor standard cleaning system under our ISO 6 clean room environment. NQW`s high production technologies and a total processing capability from glass substrate cutting to the film coating allow us to propose various kinds of Thin Film Products.
