19 December 1986 A Null-Lens Design Approach For Centrally Obscured Components
Author Affiliations +
A null-lens design approach for centrally obscured components is described. This opti-mization method, which explicitly takes advantage of the obscuration, can achieve improved wavefront quality of the null test for a given level of lens complexity than a design approach that does not take advantage of the obscuration. The fabricated aspheric part, while likely to be different in shape from that predicted by the null test by a constant phase factor, will still allow satisfactory performance of the system.
