Abstract

With latest significant improvements and changes in optical sensors characteristics it is inevitable that optical system requirements are getting tougher every day. In this work we would like to show benefits of taking a side step from rotational symmetry in optical systems design, introducing freeform optical elements, that can be a good instrument to push optical specifications to required level, especially with latest achievements in optical elements manufacturing and assembly. Main optical characteristics that can be addressed by applying freeform are optical / SMIA TV distortion and field curvature / astigmatism with most promising results in small total track wide angle and telephoto applications. In this work we would like to show main steps of design process as well as comparison with conventional rotationally symmetric optical systems.
