Put lenses and mirrors on the rail, aim a beam through them, and watch 👀 the rays bend in real time ⏱️ while the numbers 🔢 that matter — effective focal length, image 🖼️ distance, magnification, spot size — update with every millimetre you move.

THE BENCH
Drag ✋ a component along the rail to position it, select it and pull its handle to tilt it, long-press for duplicate, lock or delete. Add parts from the palette, then slide the source at one end or the detector bar at the other. The ray diagram 📊 redraws as you go, so a setup is understood by watching it rather than by solving it on paper.

THE LIGHT
Choose the source that suits the experiment: a parallel beam, a fan, a single ray, or an object arrow when you want to see 👀 the image 🖼️ itself. Set how many rays to trace, pick a wavelength anywhere across the visible spectrum, or switch to white light and watch dispersion pull the colours apart.

THE READOUT
Above the diagram 📊: effective focal length, image 🖼️ distance, magnification, RMS spot size and throughput, with the image flagged as real or virtual, upright or inverted. Everything that a bench and a ruler would tell you, without the bench or the ruler.

COMPONENTS
A library 📚 of optical parts with the properties that define them, so the difference between two lenses is a number 🔢 you can read rather than a guess. Any setup worth keeping goes into saved setups and reopens exactly as you left it.

CHALLENGES
Set problems to solve on the bench: reach a given magnification, form an image 🖼️ at a fixed distance, keep the spot under a limit. The bench checks the result, so you find out whether your reasoning held.

ANALYSIS AND JOURNAL
The analysis view breaks a setup down beyond the headline numbers 🔢, and the journal keeps what you built and measured, turning a session ⏱️ of experiments into a record you can return to.

Bronze Gladiator is for physics students working through geometrical optics, teachers who want a demonstration that reacts instantly ⚡, photographers curious about what glass actually does, and anyone who would rather move a lens and see 👀 what happens. ## Rankings - #3,192,923 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.CAMERA` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.VIBRATE` - `android.permission.WAKE_LOCK` - `com.android.vending.CHECK_LICENSE` - `com.google.android.c2dm.permission.RECEIVE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` - `com.scotiabank.onedebit.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [Pocket Optics](https://chrome-stats.com/d/com.pocketoptics) — 60,719 users, 4.32 / 5 - [LumenCite](https://chrome-stats.com/d/com.yubrlumencite.stuvwxzeducation) — 258 users - [Light Analyzer (need Diffracti](https://chrome-stats.com/d/com.ionicframework.lightanalyzer) — 37,883 users, 2.63 / 5 - [RayBend: Light Refraction Lab](https://chrome-stats.com/d/com.hhco.raybend) — 40 users - [OptikkAstro – Fokus & Linse](https://chrome-stats.com/d/com.optikkastrofo.optikkastrofokuslinse) - [Pinhole Lab](https://chrome-stats.com/d/com.pf7bb8814.pinhole_lab_package_name) — 130 users - [Laser Lab](https://chrome-stats.com/d/com.laserlab.laserlabapp) — 136 users - [Foucault Bench](https://chrome-stats.com/d/com.p9e2ceac1.name_foucault_bench_package) — 104 users - [RayPlot: Prism Optics Lab](https://chrome-stats.com/d/com.ffassoc.rayplot) — 3 users - [FluxLens](https://chrome-stats.com/d/com.rkuy.fluxlen.nmqzt) — 2,178 users - [Lens Glass Guard](https://chrome-stats.com/d/com.coasttocoast.glassguardlen) — 4 users - [Lens Sim 2020](https://chrome-stats.com/d/com.Gustaminas.LensSim2020) — 59 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.scotiabank.onedebit)
