Optical simulation that runs in a browser tab
Design thin films, waveguides, gratings, resonators, and beams with real simulators and instant results. No install, no license server.
Physics you can trace
Clean interfaces in front, documented physics behind. Every method’s assumptions are published.
Instant by design
Results arrive as you type. Change a parameter and the curve moves. Explore freely and then optimize.
Built to share
Simulations travel as links. Send one, and a colleague opens the exact setup, nothing to install.
What’s live
Real simulators, in the browser
Every tool opens in one click and computes instantly. No install, no download. Start with any of them.
Exploration is always free. Plus adds persistence; Pro adds production-grade compute.
Learning, built in
Understand first, optimize later
Learning and doing are the same activity here. The Academy teaches each concept on the same simulator you design with; the Guides walk from a real problem to a real design. The concept you just read is the simulation you’re already running.
