WebB. Use a spherometer to measure the radius of curvature of both surfaces of your lens. See Appendix (i). You begin by finding the “zero” position, x. 0, using a scratch-free spot on your bench (which is a good approximation to a flat surface). Then perform the measurement with your lens in place, x. 1; the distance . h. is then x. 0-x. 1 talbot\u0027s online catalogIn general the spherometer consists of: A base circle of three outer legs, a ring, or the equivalent, having a known radius of the base circle.
