Thin lenses Lenses are commonly used to form images by refraction. We discuss about spherical lenses only. They are part of two spheres. There are two types of lenses Converging Diverging When the thickness of the lens is negligible, the lens is called thin lens. Principal axis: the line that goes through the two centers of the two spheres. Paraxial rays are those close to the principal axis. Lenses are used in optical instruments Cameras Telescopes Microscopes converging diverging Principal axis Principal axis

Focal Length of a Converging Lens The parallel rays pass through the lens and converge at the focal point The parallel rays can come from the left or right of the lens
