Efficient performance assessment is essential during the design of systems involving complex aspheres. We present new classes of pupil sampling schemes that, with a reduced number of rays, yield accurate estimates of the RMS wavefront aberration over a circular pupil. It turns out that the number of samples in the pupil can be reduced by a factor of about 0.7, and these ideas can also be expected to lead to a similar additional reduction factor when averaging over the field and color. Beyond that, analysis of a patented lens system is used to establish the path to further significant reductions.

Keywords: aspheres; cubature; optical design; optimization



Greg W. Forbes

Greg W. Forbes is an Adjunct Professor in Physics at Macquarie University (Sydney) and the Director of Scisense Consulting Pty Ltd. Following his PhD in Theoretical Physics at the Australian National University, he was a Fulbright Fellow at the Optical Sciences Center (Tucson), a tenured faculty member of The Institute of Optics (Rochester, 1985–1994), a Research Professor at Macquarie University (Sydney, 1994–2000), and a Senior Scientist at QED Technologies (2000–2015). Throughout his career, optical modeling has remained one of his primary interests.
