Optics and Optical Design - The Third Order Aberration Coefficients of Aspheric Surfaces

In this video, you will find the expressions for the aspheric corrections to the third order Seidel coefficients for the five geometric aberrations. Example calculations for an aspheric reflector and for an aspheric lens are presented. Sorry about the somewhat poor screen resolution. Somehow I managed to upload this video at only 480p. Not the best resolution for spreadsheets. 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. OpticStudio is a product of Zemax (www.zemax.com) For those of you following the computation, at 08:30 I blurred out two extraneous minus signs (typos only), making the equation look a little odd. That's what's going on there. Also, I noticed that I never explicitly showed the numerical value for S_IV, which is +0.007612. You can see how the slide without the typos at the bottom looks here: https://youtu.be/2echc85PoYA 8:22 Typo - the ratio (y*bar)/y is cubed - not squared.
