Depth-of-Focus and its Association with the Spherical Aberration Sign. A Ray-Tracing Analysis

Purpose: To investigate the relationship between the sign of spherical aberration (SA) and the corresponding depth-of-focus (DoF) values around best focus, at three different spatial frequencies (SF). Additionally, to study the influence of the Stiles-Crawford effect (SCE) on DoF. Methods: We modele...
