Optics and Optical Design - Computing Petzval Curvature - 3rd Order Field Curvature Aberration

This short video covers the Petzval contribution to 3rd order field curvature and gives an example which includes the use of a single-glass field flattener. Please consider clicking on "LIKE". I don't get paid for creating this content, and your positive feedback is the only encouragement that I receive to continue creating this kind of helpful material. I make a lot of videos showing spreadsheets and MatLab code that are useful for optical design. The purpose is to help people who wish to make their own spreadsheets, or to write their own code. Please don't ask me to post my own files. Write your own. That's the idea. Introduction to the paraxial ray trace equations https://youtu.be/g-mPisltcRQ Chromatic aberration https://youtu.be/eYkN8KQbRKk A very thorough guide for YNU spreadsheeting, and an important resource to help you work through your own spreadsheet, is the "Pencil of Rays" website https://www.pencilofrays.com/lens-des... My favorite book reference for this is Introduction to Lens Design With Practical Zemax Examples by Joseph M. Geary. Reference: Joseph M. Geary, Introduction to Lens Design: with Practical ZEMAX(R) Examples, (Willmann-Bell, Inc., 2002), Chapter 14.
