@@aleksandarhaber i'm new to the COMSOL optical module and optics in general. Videos like yours that explains theorical concepts and the simulation afterwards are just what i'm look for. thanks
Thank you Cahit for the nice comment! I am planing to make a video on how to compute wave-front aberrations in COMSOL and another one on spot diagrams that are important for optical design. Have a nice day! A. Haber
THanks for your prompt replay @@aleksandarhaber I am new with comsol, and found very academic your tutorial. I would have liked to have the second part. I dont know how to simulate teh parallel rays coming from an object at infinity. I guess it is easy but as I am new, it may be hard for me to figure it out how to do it. I guess it is somthing like an extended light source release not a cone of rays but plane waves-like instead of an object point source from which emege the cone of rays.. thanks any way, your tutorial is very nice. Congratulations..

Hi Aleksandar, Thanks for these excellent videos. I use comsol and sometimes when the incidence angle becomes very low I the rays go through mirrors ? do you have any idea about the origin of this problem ? Thank you again
I think that you have to play with the boundary conditions when specifying lens properties. My COMSOL license just expired and I will check this once I get a new one. Best, Aleksandar Haber

Excellent video! Very clear and insightful. Waiting for the next one!
Thank you vitorhugoRH
, next video will be about optical aberrations in COMSOL multiphysics and how to compute Zernike polynomials.

@@vitorhugoRH Glad that I can help. Best, A. H.
Hi Aleksandar! Thanks for optic tutorial. I'm waiting new contents!

A nice instruction about COMSOL!Thank you.
Glad it was helpful!
dou You have the second part of this tutorial, where the object is at infinity and reach the focusing lens ?
No, I do not have.

@@rvillago Currently, I am busy with other stuff. In the future, I might create such a tutorial. Thank you! Aleksandar Haber

I am using COMSOL 5.5.
