Abstract: Today most lapping and figuring calculations are based on two dimensional rather than the true three dimensional geometry. This is equivalent to assuming the lens surfaces are planes rather than spheres. For most single surfaces (and this includes all figuring calculations) this is quite adequate since the deviations from reality are usually less than the noise or indeterminacy of pitch lap geometry. However, they are inadequate for deep spheres, deep lens blocks, and to answer questions of subtle cummulative effects.
