About OpticSketcher

A web tool for optical sketching and ray tracing in the browser.

What is OpticSketcher?

OpticSketcher is a free web tool for sketching optical systems and tracing rays in 2D and 3D. It is built for researchers, engineers, and students who want to try ideas quickly in the browser.

The goal is a reliable, accessible workspace for early design and teaching. OpticSketcher is actively maintained, and feedback helps decide what to improve next.
