Abstract

In 1974 Simpson, et al. showed how a half-silvered Hindle sphere could be used, in conjunction with auxiliary null optics, to test convex paraboloidal and hyperboloidal surfaces. An extension of this concept has been made. A partially-reflective surface and a nearly aplanatic surface form a single-element, low-power null lens which can be used to test a particular ellipsoid or hyperboloid. Two embodiments of such a lens have been constructed to test convex ellipsoids. The singlet null lens is used in a Fizeau configuration. It provides superior correction to a more conventional null lens, is insensitive to misalignment, and is calibrated by test in a stand-alone mode.
