Radius of curvature (ROC) has specific meaning and sign convention in optical design. A spherical lens or mirror surface has a center of curvature located either along or decentered from the system local optical axis. The vertex of the lens surface is located on the local optical axis. The distance from the vertex to the center of curvature is the radius of curvature of the surface. 網頁2024年11月16日 · When an object is placed at the center of curvature (C 1) or focus (2F 1) of the convex lens, the image formed after the refraction will be on the center of curvature (C 2) or focus (2F 2) on the other side of the lens. The size of the image is the same as the size of the object. The nature of the image is real and inverted. tina skidmore
