The well-known Maréchal's method for aberration tolerances has been studied only from the theoretical point of view. The purpose of this paper is to outline this method and to apply it to several simple cases of optical system with spherical and parabolic reflectors. A relation between the maximum permissible focal length and the field angle is derived in a functional form with F-number and object distance as parameters. Lastly, the form of the image surface is determined on which the Strehl definition becomes maximum. Only the third order aberration is considered, therefore the range of validity, is limited only to small field angles and large F-numbers.
