This presentation is a brief introduction to the Double Gauss photographic lens. The design procedure described is based on the work of Walter Mandler.
Hello Frank, Really appreciate your tutorial. The fourth order aberration you mentioned in the video I assume you are referring to as the wavefront aberration right? and its derivative is the 3rd order seidel aberration. thanks!
I'm assuming you are referring to the spreadsheet calculator for the thin cook triplet. The equations here are in Excel formula. Analytic solutions for this lens system are possible using ABCD matrices or Gaussian reduction. The spreadsheet solution here is solved numerically. The intent here is to supply the user with this spreadsheet.
Just as brief FYI it’s pronounced Leyets not Leets. You wouldn’t say Eezenhower (Eisenhower). When in the middle of a word, in German “ie” is phonetically a long E where as “ei” is a long I.

Wonderful (even 10 years later!)
Thank you.
Very well done my friend! It has helped me understand the Double Gauss design much better.
Thank you very much. Now I know why the 6 element double gauss lens in the zemax samples produce excellent simulated results
great video. great for myself as a neophyte optical engineer. :)

how you made the calculation in step 1?
the first eq. is above, what is the second one?

the second equation is from BFL
Very informative - thanks
You're very welcome. Very pleased you found the presentation informative.

Louis R. Zurn Good to know. Will be in Germany soon
I should be studying for a test tomorrow. I don't even know what this lens does. God help me.
