Optical design software is a powerful tool to get all the metrics of an optical design. Nevertheless, an optical designer also knows how these numbers are computed. This video covers DIY spherical aberration calculation using a YNU spreadsheet. The result is benchmarked against Zemax.

This video is a follow-up to my video about paraxial ray tracing with a YNU spreadsheet [ Ссылка ]

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.

Don't need the background? The spreadsheet calculation starts at 11:27.

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.

Starting at 9:37 there is a little typo you might have notice. The "y" is missing its subscript "i", which refers to the ith surface.

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 [ Ссылка ]

My favorite book reference for this is Introduction to Lens Design With Practical Zemax Examples by Joseph M. Geary.
