Abstract
An apparatus for measuring the curvature radii of spherical and cylindrical surfaces is provided. The apparatus comprises a base, a probe and four ball rings of the same size, wherein the four ball rings are provided on the base and arranged into a square having a side length C. The probe is upward and downward movably mounted on the top surface of the base at the center of the square. There is also provided a method for measuring the curvature radii of spherical and cylindrical surfaces, wherein a ball-ring-distance is equal to C for the cylindrical surface or is equal to .sqroot.2C for the spherical surface.
