Very interesting to a photographic hobbyist. Never heard of Zemax, so learned several things watching this video. Good pace, too, with right amount of talk. Will look at a few more on the channel. Matt Lee.
Thanks for the video. I have a lot of question in how to setup the merit function. I search every operant that you show in this video (min: 6:45) and it really help to understand some things. I try to practice designing some triplets to reduce field curvature and is really hard to setup a merit function that converge to something realistic. I will really appreciate a tutorial explaining how to built a nice merit function to constrain effectively the lens design. Thanks for your help.
@eatbobsass The Double Gauss has lower ray angle's of incidence and therefore will be less sensitive to assembly errors. Thanks for the question. Who is bob and does he have a lot of sass?
Hey @opticsrealm - great video! I love Kingslake's History too. But what confuses me - the colors of crown/flint on the diagrams.. Which one is which? Blue = flint and pink = crown, or vice versa? Because from what I'm used to, it's this way, but You point and name them in opposite direction.. Thanks. :) Hope You'll make some new videos in the future. :)

3d artist here. trying to simulate camera lenses in renders. started going down this rabbithole a week ago and now im here. i want this program.
welcome to physics, where things are terrible, but true.
Great video on a different optimization style
Also the blind optimization takes ~100 iterations to get the form, where-as using solves you get the form in ~20 iterations.
