As optical engineers, we are in charge of more than just the design and implementation of optical systems for specific applications: we often need to evaluate optical systems’ performance or to assess the quality of optical components. To do these assessments,...
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...
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...
Many of our LED optical design projects start with a simple calculation. Basically, we tell a client how much mechanical space they need to reserve for a lens to achieve the beam angle or pattern they want. In all cases, the larger the LED chip, the bigger the optic...
