摘要：A method of testing a convex mirror surface figure in which an optical qualitysubstrate material is used having a convex front surface and a rear surface polished to aprecise optical figure to create a lens. The lens is then tested by a standard

interferometric or wavefront lens-testing method and the convex surface coated once adesired curvature is obtained. Null testing may be attained by passing a collimatedinterferometer beam through a focusing lens shaped to counter the predicted sphericalaberration introduced by a perfect convex mirror/lens.
