| Who should attend: Optical engineers who wish to learn more about modeling illumination systems and performing stray light analysis with ZEMAX. |
| The course covers non-sequential ray tracing, sources, detectors, objects, ray splitting, scattering, ghost analysis, stray light analysis, prisms, Fresnel lenses, multi-element lenses, gradient index, polarization and thin film modeling. |
| Pre-requisites: We assume some knowledge of the sequential ZEMAX user interface for this class since some exercises start in sequential and move to Non-Sequential ZEMAX. However you do not need any prior knowledge of illumination system design or stray light analysis to benefit from this class. |
If your designs involve hybrid sequential/non-sequential ray-tracing, please note that sequential ray-tracing is not covered in this class. You should consider also taking Optical Design Using ZEMAX if you are not familar with sequential ray-tracing. |
