SMS illumination optics design method

LPI has completed development of the Simultaneous Multiple Surface (SMS) design methods that was first conceived in the 1990s. This is the most advanced method of its kind in the field of nonimaging optics. It has 2D and 3D variations and is used to design a wide range of optics, especially for applications in illumination and solar energy concentration. The 2D method typically results in optics with linear or circular symmetry, while the 3D method is used to design free-form optics (such as automotive headlights). There are 55 patented families of optics associated with the 2D SMS alone!
