Fig of spherometer
Webspherometer: [noun] an instrument for measuring the curvature of a surface. WebSpherometer A spherometer is used to find R, the radius of curvature of the lens. The lens is a segment of a sphere of radius R. The three legs of the spherometer form a equilateral triangle of side C and lie on a circle of radius a (Fig. 8.3). The zero of the spherometer is checked using the plane surface of the optical flat and the

WebA spherometer is used to measure the radius of curvature of a spherical surface. Most lenses have surfaces that are either spherical or close to it. For such surfaces, a spherometer provides a simple way to verify that the curvature is correct. The basis of the method is that the sag of a spherical cap can be measured and from this measurement ...

WebSpherometers. A 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.
