Offner optical relay

Webbaround a modified Offner optical relay (e.g., Baranec et al. 2007) with input and output focal ratios of f/10 and f/13.25, respectively. A schematic layout of the system is shown in Figure 1. This optical relay provides a flat pupil position just before the second mirror (AOM2), where we place a curvature DM consisting of 36 elements.

WebbIn the CAM, M2 is a convex mirror.) To maintain the essential symmetry in a true Offner, the aperture stop is at the surface of M2. 11 If the stop of the system cannot be at M2, the ideal symmetry of the relay is compromised. For CETUS, the optical design of both the MOS and the CAM encounters and addresses this issue by modifying the Offner ...
