Ray tracing and analysis

9 articles · Each with a video tutorial

QUADOA® combines sequential ray tracing with multi-sequential ray tracing, so several ray paths can be analyzed in one model. These articles cover sequences and ray tracing settings, polarization, ghost reflexes and the analysis of results.

Sequences and ray tracing settings

Auto sequence

How the default auto sequence is defined and how rays are traced through a system of several lenses.
