Toroidal mirrors are aspheric mirrors where the curvature of orthogonal horizontal and vertical axes is different. For optical products where a small, focused spot is needed, toroidal mirrors combine focusing and beam folding capabilities in a single element. This improves energy throughput, saving money, and allows for more compact designs. Toroidal mirrors also correct for the astigmatism that results when a spherical mirror is used off axis.
