Optical Lenses

Definition: Optical lenses are transparent components (usually made of glass or plastic) that refract light to converge or diverge beams, used in imaging, focusing, and beam shaping.

Types of Lenses

• Convex Lens (Converging): Thicker at the center; focuses parallel rays to a point. Used in magnifiers, cameras, and telescopes.
• Concave Lens (Diverging): Thinner at the center; spreads out light. Used in correcting myopia and laser beam expansion.
• Plano-Convex / Plano-Concave: One flat surface; used in collimating or focusing light in optical systems.
• Double Convex / Double Concave: Both surfaces curved; for short focal length applications.
• Aspheric Lens: Non-spherical surface; reduces aberrations. Ideal for high-precision optics like camera lenses.
• Cylindrical Lens: Curved in one direction; shapes laser lines or corrects astigmatism.
• Ball Lens: Spherical lens; used in fiber coupling and endoscopy.
