When to use Einstein Ring 3D Explorer
Use this explorer when you want to see how gravity bends light into rings and arcs, and skip it when you want the redshift of light or the geometry of curved spacetime.
- Classroom demos of gravitational lensing and Einstein rings
- Showing why alignment turns a ring into arcs and multiple images
- Connecting light bending to the 1919 test of general relativity
This is an educational visualization with an exaggerated ring and illustrative light paths, not a ray-traced lens model.
Einstein ring key figures
| Quantity | Value |
|---|---|
| Einstein radius | theta_E = sqrt(4GM/c^2 x D_LS/(D_L D_S)) |
| Sun's grazing-light deflection | 1.75 arcsec (Eddington, 1919) |
| First Einstein ring | MG1131+0456 (1988) |

Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
