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.
Here I derive the ray transfer matrix for the thin lens from the transfer matrix for refraction at a curved surface. When we do so, what we actually get is the lensmaker's equation, which gives us the focal length of the lens.
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.

Awesome video, super helpful. I was wondering, what would be the transfer matrix for a concave lens? thank you

Hello, thank you always for your helping videos:) Do you mind making one regarding the thickness of the lens as more than 0?? And I’d be more than happy if you post videos of how to derive the ray transfer matrices for flat and curved mirrors too.. Please consider making them:)

How to derive a relashionship between the incident and the refractive angles in thin lenses ?

In the matrix formalism,what advantages do we get if we consider the lens to be thin??

Great question. Basically we can apply two refraction matrices and don’t need to worry about an extra propagation matrix in between the two surfaces.

I have a question.. Shouldnt it be R2
@JordanEdmundsEECS 2 жыл бұрын
In general, R2 can be negative or positive, but you will want to subtract 1/R1 from 1/R2 because you're going from low refractive index -> high refractive index in one case and high refractive index -> low in the other case.
