Freeform mirrors are curved optics with no axial symmetry and offer many advantages over conventional optics. Their single optical surface allows for compound compensation and a reduction in the number of optics in the system, reducing optical volume, easing alignment and improving throughput. They also provide additional aberration correction and allow for redistribution of tolerances.
