LENS
An optical lens is a device that forms an image by refraction. A simple lens consists of a single piece of glass, or other transparent material, havingtwo opposing faces, at least one of which is curved. The "burning glass" for concentrating the sun's rays has been known since ancient times. The magnifying property of a simple lens was recorded byRoger Bacon in the 13th century.

CONVERGING LENSES
A lens is said to be converging, or positive, if light rays passing through it are deflected inward, and diverging, or negative, if the rays arespread out. Converging lenses are thicker at the middle than at the outer portion, while diverging lenses are thicker toward the edges. The surface of a lens can be: – concave (curved inward) – plane(flat) – convex (curved outward)

FOCAL LENGTH
The focal length of lens is the distance from its optical centre to the focal plane (the point at which incoming parallel rays focus), when focus ringihs set at infinity. Infinity, for sake of argument when dealing with practical camera lenses, is sixty metres away. Long lenses (zoom lenses at tele, maximum zoom) have less depth of field thanshort lenses (zoom lenses used for wide shots).
