Non-Imaging Optics Overview

In applications requiring a narrow beam or a small target, conventional illumination design falls back on lenses and parabolic or elliptical reflectors.   These "imaging" elements are initially designed based on point sources or targets, and then optimized for more realistic objects.  But in many applications this point-source approximation is a bad one, and even the most highly optimized systems can fall frustratingly short of design goals.  Non-imaging optics breaks this performance limit by basing the design on non-point (real-world) light sources from the outset.  This novel approach produces unique, computer-generated shapes that control the full angular and spatial content of the source or beam. The innovation is in the shapes--our designs use standard materials and fabrication methods, so cost and lead-times resemble conventional custom optics.  Reliability is usually improved, so overall system costs are often lower than with conventional approaches.
