Abstract
Corrector plates for Schmidt-Cassegrain systems are subjected to equivalent focal length changes if the neutral zone varies from the established 0.86 zone. Fabricating a plano-convex element first, before changing to a corrector plate (C .P.) removes almost 50% slope departure. Shifting of the neutral zone is caused by the non-control of the grinding with glass tool rings. The control of the neutral zone can be accomplished by other fabrication methods.
