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. The uncertainty R in the radius of curvature R is ...
