What is another word for crown lens?
Pronunciation: [kɹˈa͡ʊn lˈɛnz] (IPA) 
A crown lens is a type of lens that is thicker in the center than at the edges. This gives it a curved shape that allows light to bend and focus on a point. Other synonyms for crown lens include convex lens, positive lens, and converging lens. Convex lens refers to its curved shape, while positive lens means that it magnifies images and has a positive focal length. Converging lens, on the other hand, describes how it brings parallel light rays together at a common focal point. Regardless of the term used, crown lenses are an important component of many optical devices, including glasses, cameras, and telescopes.
