@Salama: I suspect you've correctly entered the parameters and you're using the layout window to confirm your changes. The layout window at time stamp 1:45 is drawing surfaces 1 through 3. At time stamp 2:15 you have inserted two surfaces after the object. The layout window is probably drawing only surfaces 3 through 5 making it appear as if nothing has changed. In the layout window click the settings pull down or right click on the window and set the "first surface" (upper left) drop down to 1
Hello Scott. Do you mind explain exactly why you wanted flip the first lens? Or what are the rules which material should be first, which plane the rays should be facing first. Ye I know it depends on situation probably but say for imaging purposes or laser beam expanding. Thank you. This channel is hidden gold. 🥇
In general, it's best to have a higher curvature surface interface with the collimated rays. This can lower the angles for the rays in snell's law at each surface, which makes the system behave more linearly and thus have less aberrations.
I got as far as 1:45 (the telecentric eyepiece), but when I insert the additional lens and give it all the parameters described in the video, the layout does not update to show it. I've also added the field data up to 2:15 to no effect. What am I missing?
I've a question: when i click ''insert'', zemax asked me about surface ('' Insert to Surface"). what surface should i choose? cant understand this moment =(
Xac, I assume the "insert" click comes from the dialog box to insert a catalog lens. If that is the case, then choose the surface where you are replacing the paraxial lens if it has been deleted already. If you have not deleted the paraxial lens, select a surface before or after the paraxial lens you are replacing (then don't forget to delete the paraxial lens - otherwise your system will "double up" on that lens). Hope this helps, and if not please post more comments!!!!
Checking back to the original Zemax files, "Float by stop size" was used for both the paraxial lens configuration and for the lens using off the shelf doublets. I used a stop semi-diameter of 5.o in the "Semi-Diameter" column in the LDM (Lens data manager).
When I get stuck on my android or iPad, I get my kids to fix it. They do it by clicking and messing with stuff I had never considered. At some point I need to teach my kids Zemax so they uncover all the hidden gems I am unaware of....:)

all these videos are very helpful. Thanks so much
Thanks!!!!

Can you change the refractive index of the paraxial lens?

Hi Scott,
Thank you very much.
Where did you define the F# in this tutorial?
I mean should I end up this in the Gen tab/Aperture type?

What does this modeling look like in real life?
Bingo. Thanks. For me the hardest part of lens design is learning the idiosyncracies of the software.
