Abstract

Astronomical aspherical mirrors may be tested in the optical shop with a Hartmann null test. A null test is obtained by placing small wedges over each hole of the Hartmann screen. The wedges have an angle between the two faces such that the spherical aberration with the object and the image at the center of curvature is just compensated.

摘要

大型非球面镜可在光学车间用哈特曼零位检验法进行测试。通过在哈特曼屏的每个孔上放置小楔块来实现零位检验。这些楔块的两个面之间有一个角度，使得物点和像点位于曲率中心时的球差恰好得到补偿。
