Abstract

A method of balancing the optical aberrations over a wide angular field of a Schmidt optical system is described. This design method is demonstrated for a Schmidt optical system of focal ratio F:0.7 and covering an angular field of 40°. The reduction in off-axis secondary aberrations is obtained by computing a “wide angle” aspheric corrector plate through the use of “Lucy’s Approximate Method” instead of using the conventional “exact equations.”
