Let PF = f, the focal length and PC = R, the radius of curvature of the mirror. AB is an object placed in front of the mirror perpendicular to its principal axis. A B is the virtual, erect image of the object AB formed (behind the …
WebAny surface that is curved has a radius of curvature, the radius of the sphere that approximates the surface locally. Thus a spherometer can measure the radius of … WebA spherometer is an instrument for measuring the radius of curvature of a spherical lens or mirror surface. It may consist of a ring resting on the surface, with a micrometer plunger in the middle of the ring to measure the sag of the surface from the plane of the ring. Visit Website Request a Quote.

WebTools. Radius of curvature and center of curvature. In differential geometry, the radius of curvature (Rc), R, is the reciprocal of the curvature. For a curve, it equals the radius of the circular arc which best approximates the curve at that point. For surfaces, the radius of curvature is the radius of a circle that best fits a normal section ...
