Yes indeed. The color-corrected landscape is up next, then the Cooke and double Gauss, with a few bonus videos on specific techniques. Then I'll be going through the auxiliary series. The goal is to have a pretty comprehensive series on imaging optics using 21st century design methods.
Shrinking the lens down to cell phone size was a great demonstration. Could you cover plastic vs glass materials and how you deal with abberations when using plastic?
Amazing video Sir. I have a question regarding optimizing the last lens surface using f#. Does it only work with a singlet or can we use this F solve on the last lens surface's radius in a multiple lens systems?
@@marknicholson5508 I was wondering, why the quality of the zero field point increases with the reduction of focal length. The spot size is a function of the f-number only, correct? And it stays the same when you use make focal...
@@alexsandra1009 I think the *diffraction limited* spot size doesn't change, that's 1.22*wavelength/f# but the geometric spot will as aberrations reduce. Of course, the real spot cannot get smaller than the diffraction limit, but the geometric spot shows the effects of aberration balancing even though it's not observable.

This is a great series, thank you for putting this together. It's so helpful to see the end-to-end workflow and good practices with the software!
Great video! I hope this is the beginning of an entire series on optimization of the different lens types you presented earlier.

Yep, that's coming later.
At the end of the video, we didn't obtain the desired specifications desired at the beginning. Did I miss something?
It's just that this Basic Shape cannot meet the specification, no matter what we do. You need a more complex shape.

Hi @Sanjay Kumar, you can have as many surfaces as you like. Put the f/# solve on the last radius and it will control the overall system f/#
