Compensation of aberrations by elasticity

Abstract

A new method of obtaining aspherical surfaces from elasticity is applied to the wave-front function. The primary aberrations with arbitrary amplitude are considered in detail. It is shown with respect to conventional criteria concerning a given value of the normalized intensity at the diffraction focus, that three simple loads and associate thickness configurations of the plates can be found in the case of primary spherical aberration. One configuration for simple loads and thickness is found in each case for primary coma and primary astigmatism.
