Last modified: Wednesday, February 14, 2007 

In photography and digital photography the lens is the part of the digital camera or video recorder that concentrates light and focuses the image. The lens itself is a single piece of glass (or other transparent materials) with one or more curved surfaces. Cameras usually contain a combination of lenses that receive light rays from an object and form an image on the focal plane.
