Light Beam Collimation and Expansion Diagram - Physics Visualization #1908822 (License: Personal Use)

The image shows a classic optical setup: an incandescent light bulb acts as a point source, emitting light that passes through a collimating lens (gray rectangle), producing a parallel beam. That beam then enters a diverging optical element (larger gray rectangle), causing the light to spread into a conical shape. The yellow gradient visually represents intensity falloff across the beam profile.

Used in educational materials on geometric optics, laser systems, lighting design, or photonics tutorials; matches user intent for understanding beam shaping, collimation, and divergence principles.
