Lens coatings are thin layers of material applied to the surface of lenses to reduce unwanted optical effects such as ghosting, chromatic aberration, and reflections. Ghosting is a type of optical artifact that appears as a faint copy of the main image, typically caused by internal reflections within the lens. Chromatic aberration is an optical defect that causes different colors of light to be focused at slightly different points, resulting in a loss of image […]
