N2  - A study of the geometrical optics of a concave spherical mirror is made over the range of incidence from normal to grazing.   An examination is made of methods of correcting for astigmatism at oblique incidence by the use of &quot; crossed &quot; mirrors (spherical and cylindrical), of &quot; parallel &quot; cylindrical mirrors, and of a single mirror with different radii of curvature in planes at right angles. Such a single mirror combines in one piece image formation and beam deviation.
