Cylindrometer

Spherometers are instruments designed to measure the radius of curvature of spherical surfaces. They are particularly useful in situations where only a portion of the spherical surface is available, for example, for measuring the radii of curvature of spherical lenses. A spherometer can be easily modified so that it can also be used to measure the radius of curvature of a right circular cylinder. The resulting device is called a "cylindrometer" (also known as the "cylindrospherometer"). The idea is quite old but is seldom mentioned in introductory laboratory courses. This paper describes the device and its operation.
