Telephoto Prime Lens Design: A Patent Study

This fourth patent study in devoted exclusively to one patent, both because of the detailed review I wanted to do, and because it is such a good patent with good embodiments. Some topics covered in this video that I haven't touched on before include stray light analysis, wave front error, and depth of field. Please consider clicking on "LIKE". I don't get paid for creating this content, and your positive feedback is the only encouragement that I receive to continue creating this kind of helpful material. My other patent studies are in this playlist:    • Optics and Optical Design   It was a race against time to finish the simulations with my OpticStudio license set to expire, and expire it did before I was completely finished. But that proved to be only a minor concern as I got pretty much everything I needed. I just didn't get to finish optimizing. OpticStudio is a product of Zemax (www.zemax.com). References: 1. The patent in this study is US patent number 3,942,876 "Telephoto Lens". The inventor is a luminary in the field, which explains the quality of the invention. 2.
