Abstract
In this paper, we compare a standard wide angle system design to an array of four off-axis micro optics systems. The reference system is a single x/y-symmetric optical system to reach full field of view (FOV) of 140°×170°. To obtain the same FOV an array of four off-axis systems, consisting of tilted and decentered freeform elements, with small sub FOVs is designed. The system design is such that a production via 3D-two-photon printing is possible. We compare the performances of the standard system to that of the array of off-axis systems.
