The Detector Volume object in ZEMAX is a very useful tool for detecting light inside a volume. It uses volume pixels, or voxels, to detect light. However, the ZEMAX interface currently allows these voxels to be viewed only in 2-D planes. This article will show you how to use ZEMAX to create intricate CAD models of the voxels in a Detector Volume, and a sample ZPL macro is given at the end of this article for use in creating these CAD models automatically.

This article describes work I did to improve an existing infrared lamp heater in a so called horizontal geometry MOCVD reactor. ZEMAX was used to model and optimize the heater geometry using non-sequential ray-tracing.

This paper described work undertaken at the University of Bern to model the cavity of a side-pumped Nd: YVO₄ laser using ZEMAX to compute the absorbed power in the laser rods and the LASCAD program to compute the resulting cavity modes.
