When light meets a surface, some of it is reflected away, reducing brightness, contrast, and overall clarity. An anti reflective coating—often abbreviated as ARC or AR coating—is a specially engineered thin film layered onto lenses, screens, imaging elements, and other optical surfaces to minimise these reflections. The result is improved light transmission, sharper images, and…
