| Modeling a Koehler Illumination System
One can mathematically determine how to configure a source and two lenses into a Koehler Illumination setup. The process can be simplified by using the paraxial approximation and enables an initial lens selection. Important: Once lenses are selected, optical design software such as Zemax, CodeV, or FRED should be used to analyze and revise the system as needed. Performance will vary based on source and lens selection. |
