One important aspect of any design is user safety. This is especially important when using light sources like lasers and LEDs that may be observed by the naked eye. Disregarding safety can lead to product recalls, lawsuits, and harm to users. To protect users, a...
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...
