We present a design for a unit magnification imaging relay that is compact. The design uses two mirrors, and one is used by light twice for a three-reflection system. The mirrors are specified with freeform surfaces. There are several tradeoffs of performance depending on field of view, F/#, and wavelength range. One example provides a 30-mm circular field of view at F/2.8, and another example provides a circular field of view of 40 mm in diameter at F/4 for a length of similar to 400 mm. Adding a third nearly flat mirror allows a system to provide a 50-mm field of view at F/4 for a length of 420 mm. A last example includes a beam splitter cube to allow accessing the full field of view. These systems are diffraction limited at 550 nm.ISSN
