: Nijboer-Zernike's diffraction theory of aberration is a nearly abandoned jewel of physical optics. The present paper constitutes an attempt to extend its practical feasibility. It is found that such a task can be achieved by using what is probably the most important property of Tchebychev's polynomials.
