The goals of this guide with a spreadsheet People who want the mathematical derivations.People who are physics-like researchers that want to derive theorems.People who just want a lens design solution, without the work that comes with it.People who want a quick fix to a specific optics problem.People who are enthusiastic about lens design process, and can do trigonometry, I’ll try to make the math interesting.People who are self taught in optics to a certain degree (you can skip the math if you know it).People that started lens design through other disciplines (such as mechanical engineering, physics).People who want an applicable lens design guide.People who want the basic knowledge of lens design explained clearly, and visualized in a spreadsheet.People who want to sharpen their existing lens design skills.
Total system design require the software, but breaking the optical system down into intermediate lens groups, and understanding the choices of lenses that you are using is an acquired knowledge that can’t be learned by simply using the software.

We can replicate this with a spreadsheet.īy learning the classic method to do lens design, we will be able to dig up the properties of lenses that are required for the lens system in a way that can be easily buried when using expensive, proprietary lens design software programs. How did the people in the past design a lens, before computers came into the lens design picture? Most calculated rays of light by hand. The basis of lens design, the refraction of light itself is a relatively simple concept that we can learn in physics class such as Snell’s Law, but lens design uses those concepts in a complex configurations that is a science to itself. What you will learn in this guide, how we incorporate a spreadsheet Although the calculation methods are classic, with the help of a spreadsheet, we will do a step-by-step lens design that makes all of the steps and theory make sense.
This guide will tackle how lens design was done before optical design software on computers were invented, which I will call the “classic” method for lens design. Introduction to the General Theme About this guide (and how we can use a spreadsheet in lens design) Conceptual lens design by the masters, without using expensive software, but a spreadsheet
