Sequential Ray Tracing

Sequential ray tracing is one of the core technologies in Zemax. Sequential ray tracing is used to model almost all imaging systems, including afocal systems. It is fast, flexible, and easy to optimize and tolerance. The sequential approach is that light travels from surface to surface in a defined order. This allows a great simplification in ray tracing, as we always know which surface a ray will hit next. OpticStudio supports both sequential and full non-sequential raytracing to give you complete capabilities for any system.
