Abstract: Methods and systems for depositing a thin film are disclosed. The methods and systems can be used to deposit a film having a uniform thickness on a substrate surface that has a non-planar three-dimensional geometry, such as a curved surface. The methods involve the use of a deposition source that has a shape in accordance with the non-planar three-dimensional geometry of the substrate surface. In some embodiments, multiple layers of films are deposited onto each other forming multi-layered coatings. In some embodiments, the multi-layered coatings are antireflective (AR) coatings for windows or lenses.
