Zemax Tutorial 12 - Stops and Pupils

How to use Zemax to find an optical systems aperture stop. How to locate the image of this stop in object space for the entrance pupil and again in image space for the exit pupil.

These tutorials are amazing! A gentleman and a scholar!

I cannot emphasize enough on how much helpful you have been helpful to the Optics society.

I would love to see a video discussing the manufacturability of a lens design. Also, how to assess which parameters should be considered more important before submitting to a manufacture e.g. optomizing spot radius rms or strehl ratio

I want to ask what's the importance of finding aperture stop and entrance, exit pupil?

[@mojtabaseydi5051]

Hi, these tutorials were very useful for anyone wanted to learn Zemax including me. Why did you stop them???

Ya, it's a shame I was really looking forward to his aberrations focused lectures. He must have gotten busy and never got back to it.

Hello! Very interesting stuff. I'm getting into optics this summer for a small project concerning partial obstruction of lenses. In particular, telescopes with a 4 to 6 inch aperture. Your videos so far have been incredibly helpful, but i need an additional resource like Zemax, only not that extensive or expensive. If you know of any free software that would aid in simulating simple optical systems, that would be of great help! Thanks!

There is GOPTICAL at www.gnu.org/s/goptical/ which is a shareware / gnu / freeware software package...I'm not that familiar with how to use this software

[@opticsrealm]

There is also KDP2 at www.ecalculations.com/ but there may be some "issues" with the IP

[@opticsrealm]

There is also an education version of Oslo from Lambda research at secure.lambdares.com/education/oslo_edu/

[@opticsrealm]

Probably the best bang for you buck is Optalix at www.optenso.com/

***** I'm currently at the International Design Conference which is every 4 years... And I asked this question to most of the ray trace software folks. Oslo can get you 8 surfaces. There is also the ray trace software called "Synopsys" which is not to be confused with the company that bought the makers of Code V. "Synopsys" free version gives 12 surfaces... and can be found at www.osdoptics.com/

hey Hi...great videos, very helpful...If you can give some tutorial on Aberration balancing, selecting which surface to aspherise and A bit of explanation of Default merit Function of Zemax. that will be very helpful
thanks

[@opticsrealm]

Thanks!!! The plan is to have a video for each type of third order aberration within the optics playlist and how to analyze each in the Zemax playlist. Followed by balancing / design of these aberrations and eventually aspheres. Zemax # 6 talks about the default merit function

[@AmitGupta2526]

opticsrealm thanks..!! there are very few help available in the optical design domain. I m looking forward for your every tutorial. it will be very helpful if you may give link of blog/websites or any other references available which can enhance our knowledge...

[@opticsrealm]

Amit Gupta Would a bibliography or book list on my website / blog help?

[@AmitGupta2526]

opticsrealm that would be great. Thanks for considering the suggestion
