Abstract

A method for the design of nonaxially symmetric optical systems using free-form surfaces is proposed by researchers. Attention was placed to have an F-number of 2.0 in both principal sections of the telescope as the RMS spot size highly depends on F-number. The distortion aberration, smile and keystone of the design is 3.36%, and there is negligible image plane tilt with respect to the optical axis ray. The researchers have corrected the error in the comparison we made in their paper by properly scaling up the three-mirror system and re-optimizing it to account for the scale change, and for the fact that the optimization of the f = 35.7 mm system was stopped earlier when it reached close to diffraction limited performance.
