- Aperture stop: Constrains the on axis beam. Seen from object space is the entrance pupil. Seen from image space is the exit pupil. Also shows how to telecentrate an existing lens.
Thank you Scott!
I finally know what is entrance pupil and exit pupil.
yes. finally a clear explanation for locating entrance pupil and exit pupil locations via oject/image extended ray. thank you so much. this saved me a lot of headache and wasted time.
Good illustration on stop and pupil. Really like the combination those locations with double gauss lens.
Thanks for this great resource, for taking you time and share your knowledge.
No one can explain better than this one 👀
Thanks Scott. Looking forward to your tutes on spherical aberrations and apochromats
Hands off sir, great explanation. Can you please do a video on the design complete from scratch like design of a microscope or telescope?
Thanks for presentation of this challenging subject.
I'm just doing an overview again! Now, I'll go back and concentrate on them all!
event with one lens a stop can exist inside.This how Galilleo improved his telescope
Thank you so so much
Thanks a lot, this is really a good explanation.
Thank you so much, Scott! Can you explain how to set EPD and STO? I am confused about this when I am using Zemax. BTW, your tutorials are awesome!
hi, scott:
thanks a lot for these tutorial videos, which very detailed and informative!
A quick question, for a blackbox optical system, you have showed how to identify the size and position of entrance/exit pupil. Is there a way to know where the actual optical stop is or size? seems that we have to know where chief ray crosses optical axis...
looking forward to your insights
thanks

Good tutorial. Can you talk about how to match the exit pupil of one optical system to the entrance pupil of another in order to make them work together.
Good idea! I'll do that in the next video. Next video I was planning on discussing Field stops. which can be a great place to put lenses for pupil matching. Truth be told, the original optics video #12 I had discussed pupil matching by telecentrating, but that is a sub optimal place to pupil match. A better location is at an intermediate image by using a "field lens"
Dear Sir many thanks for the upload, i was trying to go through the problem 1 . entrance pupil is at same location as that of aperture stop , but for finding exit pupil it was bit difficult for me as i can't trace back with the chief ray as it becomes parallel after passing through second lens. I need your help since i am not able to get the solution on your site as well, due to inactive solution link.

thx, scott, can u share answer the questions? on your site.
Hello
Do you have any bibliography , please?
Thanks for the info
Scott Do know anyone who will do Zemax designs for $??
