They don't measure sphericity, i.e. how spherical your surface is. Spherometer is a misnomer. As I sad earlier, spherometers can find radii of curvature of concave as well as convex surfaces. Foucault/Ronchi test or drill bits can't. Oregon-raybender likes this #32 Noobulosity …

WebSpherometers made by TRIOPTICS are used worldwide in hundreds of optics companies and laboratories for the precise measurement of the radius of curvature of concave and convex lenses. The radius of curvature is determined by the tactile measurement of the sagittal height of the curved lens surface. WebA spherometer is used to determine the radius of curvature. The aim of a spherometer is to measure the curvature of a spherical surface so it can be convex or concave by using a spherometer.
