<H2>What is Nonimaging Optics?</H2>
<P>Nonimaging optics is a field that deals with the optimal transfer of light between a source distribution and a target distribution. The most common use of nonimaging optics is achieving maximal concentration of light. As detector noise or thermal radiation generally depends on the target area, one sees that detector systems and solar energy applications can benefit. Imaging systems have large aberrations which prevent ideal (or maximal) concentration.</P>
<P>Other applications use nonimaging optics to design illumination systems where a constant irradiance can be achieved on a distant target using novel types of tailored reflectors. Also, concentrators for solar pumped lasers can be optimized to better the pump power absorption distribution inside a solid state laser crystal, such as Nd:YAG or Nd:GSSG.</P>
<P>In order to keep pages small, we describe our various projects using a different webpage for each. Below is a description of the 50,000 suns experiment. After that, hypertext cues will transfer you to additional webpages explaining our other projects.</P>
