Thin Converging Lens 3D Simulation

Ever wondered how lenses form real and virtual images? Welcome to the Thin Converging Lens Simulation, your interactive 3D optics lab.

Start by adjusting focal length, object distance, and object height in real time. Watch the rays instantly respond and see how image position and size change. Switch between object modes, like candle and projection slide, to explore different setups. Use auto-focus to snap the screen to the image plane, or manual mode to find focus yourself.

Need quick examples? Use built-in presets for diminished, same-size, magnified, infinity focus, and virtual image cases. The app visualizes principal rays clearly, with optional labels and camera orbit controls. You can drag objects directly in the scene for hands-on experimentation.

Live math panels display the thin lens equation and magnification calculations as you interact, while image characteristics update instantly: real or virtual, orientation, and scale.

From classroom demos to self-study, this simulation makes lens physics visual, intuitive, and fun.
