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.
This is part of my graduate series on optoelectronics / photonics, and is based primarily on Coldren's book on Lasers as well as graduate-level coursework I have taken in the EECS department at UC Berkeley.
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.

My first thought is that the lens doesn't have to be infinitely large, it just needs to enclose the object. Not sure what that would do to the image, though

One question, so, as the angle of the marginal ray depends on the distance the object is respect to the lens, does that mean that NA (as it is the sine of the angle of the marginal ray) is dependent on the distance? I dont get it because usually on the spec sheet of a lens usually the NA is put and I dont know at which distance it is given.

What is the effect of increasing and decreasing the aperture stop diameter on the image obtained at the screen?

The main one is that the I,age gets brighter as you open up the aperture stop. You are also exposing more of your lenses, so aberrations will get worse as you open it.
