WebThe spherometer used for measuring radius of curvature of spheri-cal surfaces is explicitly based on a geometric relation unique to circles and spheres. We present an alternate approach using coordinate ge-ometry, which reproduces the well-known result for the spherometer and also leads to a scheme to study aspherical surfaces. We shall also brie WebA spherometer is defined as. An instrument that is used for precise measurements of the radius of curvature of either sphere or a curved surface. The first spherometer was …
