The title of his presentation is “Étendue and what you can Étendue with it”. Illumination engineers use the étendue for numerous radiometry calculations and optical designers use the optical invariant as an aid to system design. This talk is intended to review the concepts and present a wide variety of examples that show tips, tricks, and back of the envelope calculations that can put a different perspective on system design.
