Near-null interferometry using an aspheric null lens generating a broad range of variable spherical aberration for flexible test of aspheres

Shuai Xue, Shanyong Chen, Guipeng Tie
A null lens moving back and forth relative to a point source can generate variable spherical aberration for flexible test of aspheres. Different from the previous methods, variable spherical aberration null theory was developed by us to optimize the null lens. The optimized null was a plano-convex ...
