Optical Refraction Diagram - Light Beam Through Cylindrical Lens #119693 (License: Personal Use)

This diagram illustrates how a collimated light beam enters a transparent cylindrical optical element-such as a cylindrical lens or waveguide-and undergoes refraction, resulting in a focused or shaped output beam. The light path is shown with a shaded blue region indicating the beam’s cross-section before and after interaction with the element. The clean vector-style rendering emphasizes geometric clarity for educational or technical documentation.

Used in physics textbooks, optics course materials, engineering presentations, and product documentation for optical components; serves users seeking conceptual understanding of beam shaping, lens behavior, or photonic device design.
