/ edmundsj • If you want to see more of these videos, or would like to say thanks for this one, the best way you can do that is by becoming a patron - see the link above :). And a huge thank you to all my existing patrons - you make these videos possible. • It would be great if we could analyze arbitrary optical systems just like we analyze thin lenses - with a single focal length. Using the effective focal length, we can do just that. In this video I explain what the effective focal length and (2nd) principal plane are, and how to find them mathematically using ray transfer matrices. • This is part of my series on semiconductor physics (often called Electronics 1 at university). This is based on the book Semiconductor Physics and Devices by Donald Neamen, as well as the EECS 170A/174 courses taught at UC Irvine. • Hope you found this video helpful, please post in the comments below anything I can do to improve future videos, or suggestions you have for future videos.
