Which is much better ?(Single or Multi-coating)
The difference between single and multi-coating is not as great as that between an uncoated and a single-coated lens; the single layer of coating deals with the majority of the reflection, and multi-coating is a refinement to further improve its effectiveness. However, the difference becomes significant when there are a large number of reflective surfaces in the lens. Multi-coating, as compared to single coating, represents a notable advancement in optical technology, particularly in the context of camera lenses and other optical systems. To understand the superiority of multi-coating over single-coating, it's essential to consider how each approach affects light transmission and image quality. Single coating involves applying a single layer of anti-reflective coating to the lens surface. This coating is designed to reduce reflections and enhance light transmission. While it is an improvement over an uncoated lens, it still allows some light to be reflected, leading to potential ...
