WebSpherometers are small precision instruments for measuring the radius of curvature of spherical surfaces. The term may also be spelled as a "spheremeter" or "sphereometer". The most common application of a spherometer is the measurement of an unknown lens shape, in order to study its optical characteristics. WebThe spherometer constant r is determined by taking the average distance between the central contact point and the three outer contact points with the spherometer zeroed. The uncertainty in r determined in this way is the uncertainty for a single measurement multiplied by the square root of 3.
