The position of the rod is determined by a micrometer screw gauge or spherometer.
Electronic instrumentation similar to the spherometer in design are modified at inspection plants for casing, tubing, and drill pipe.
This approach reproduces the well-known result for the spherometer and also leads to a scheme to study aspherical surfaces.
Since the spherometer is essentially a type of micrometer, it can be employed for purposes other than measuring the curvature of a spherical surface.
A related device is the Cylindrometer ( also known as Cylindro-Spherometer and Sphero-Cylindrometer ), which can additionally measure the right-circular cylinder
A contact-lever, delicate level or electric contact arrangement may be attached to the spherometer in order to indicate the moment of touching more precisely than is possible by the sense of touch.
To measure the radius of a sphere e . g . the curvature of a lens the spherometer is levelled and read, then placed on the sphere, adjusted until the four points exert equal pressure, and read again.
