Optics and Optical Design - Paraxial Ray Trace Equations and Building a YNU Spreadsheet, with an Example

Geometric optics. The two elementary paraxial ray tracing equations are worked out and applied to the analysis of a singlet lens. Their use in a YNU spreadsheet is described. Reference: Introduction to Lens Design: With Practical Zemax Examples, by Joseph Geary, Willmann-Bell (August 1, 2002). 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-design-spreadsheet/ #GeometricOptics #YNUspreadsheet #ParaxialRayTracing #OpticalDesign #LensDesign
