Quantitative methods for examining and describing the surfaces of off-axis parabolic mirrors are given, together with practical suggestions for the most effective use of such mirrors. Included are tests with, and without, an optical flat. In each case the theory and experimental procedure are illustrated by application to a particular mirror. The quality of a mirror is given in terms of the minimum slit width that can be profitably used with it.

  4. Two definitions: a. The principal radius: The distance from the mirror axis to the remote edge of the mirror. This radius passes through the geometric center of the mirror. b. ƒ-number of an off-axis mirror: The ƒ-number of the smallest symmetrical mirror from which the off-axis mirror can be cut. One might call the usual ratio, aperture diameter/ focal length, the effective ƒ-number of the mirror.
