First-Order Optical System Design

Optical systems are at the heart of modern technology, powering everything from smartphone cameras and medical endoscopes to advanced aerospace sensors. Understanding how light behaves and how lenses manipulate it is the essential first step for any aspiring optical designer or engineer. This text-based course guides you through the foundational principles of first-order optical design. You will learn how to use simple mathematical and graphical techniques to lay out optical systems, determine image positions, and analyze system performance before moving to complex simulation tools. What you'll learn: - Understand the fundamental behavior of light, refraction, and Snell's law in optical systems - Apply paraxial ray tracing techniques to determine image location, magnification, and orientation - Analyze optical systems using cardinal points, focal lengths, and principal planes - Configure stops, apertures, and pupils to control light throughput and field of view - Design basic multi-element systems such as telescopes, microscopes, and camera lenses - Bridge manual first-order layouts with modern computer-aided optical design software workflows The course begins with core terminology and the physics of light propagation, gradually building up to graphical ray tracing and multi-lens system analysis. You will practice through structured written exercises that reinforce real-world engineering calculations. This course is designed for beginners, engineering students, and software developers entering the optics field, with no prior experience in optical design required. Start your journey into the world of optical engineering and master the foundational math of light today.
