Abstract

The lens design problem for the 2023 IODC is to design a lens which is diffraction-limited over the field of view at 550 nm but at the same image plane location has large on-axis RMS wavefront error at 540 nm. The entrance pupil diameter and the semi-field of view are not specified, but are free to be selected by the designer so as to maximize the product of them and the 540 nm on-axis RMS wavefront error. Only two different glasses are allowed to be used (Schott N-BK7 and Schott N-SF6). 24 entries were received from seven different countries. The winner is Arnaud Davenel of Safran Electronics & Defense in France.
