Expanding Zemax Capabilities with User Defined Objects
by AnatoliTrafimuk | illumination, optical engineering, Zemax
To assist with the computation of the paths of millions of light rays, optical engineers use specialized software to design and simulate optical systems. Zemax is the most popular optical design software and the one I prefer. It includes many built-in functions...
Advanced materials for LED optics
by John | FAQ, illumination
Since the start of the LED lighting revolution, plastic optics have been made primarily from acrylic (PMMA), polycarbonate or a modified version of either material (for example PMMI). More recently, silicon-based optical materials have grown in market share. These...
