Simple Köhler Homogenizers for Image‐forming Solar Concentrators
- Conference date: 4–6 April 2011
- Location: Las Vegas, Nevada, (USA)
We demonstrate that the Köhler illumination technique can be applied to the image‐forming solar concentrators to solve the problem of “hot” spot and to generate the square irradiance pattern. The Köhler homogenizer can be simply a single aspheric lens optimized following a few guidelines. Two examples are given including a Fresnel lens based concentrator and a two‐mirror aplanatic system.
