Geometric Lens Diagram

This geometric optical diagram illustrates how a collimating lens system works. Light rays originating from a single point on the left diverge as they approach the lens. After passing through the lens, these diverging rays are refracted and emerge as a parallel beam on the right. This setup is commonly used in various optical instruments to produce a parallel stream of light from a point source.
