WebLens. Lenses are basically magnifying glasses with curved sides. A lens is a piece of transparent glass which concentrates or disperses light rays when passes through them by refraction. Due to the magnifying property, lenses are used in telescopes and other magnifying devices. They are employed in cameras for gathering the light rays.

For example, ... or \thin lens" assumption2, it is called the paraxial refraction model. normal barrelpincushion Figure 6: Demonstrating how pincushion and barrel distortions a ect ...
