LPI has extensive experience in the optical design of nonimaging and imaging systems. These can be applied to a wide range of illumination (both high-end and conventional) and solar applications. Our highly efficient designs are developed using the most up-to-date design principles, including our own revolutionary Simultaneous Multiple Surface (SMS) design method. This method can produce free-form optics which are compatible with applications where tight off-axis geometrical constraints or radically asymmetric performance goals are needed. The devices derived from this method and other optical technologies have been patented. LPI proprietary design tools can also be customized for clients willing to carry out optical design in house.
