Lens

[hydrology] In hydrology a lens is a convex layer of fresh groundwater that floats on top of denser saltwater. It arises when rainwater seeps down through a soil surface and then gathers over a layer of seawater at or down to about five feet below sealevel. Freshwater lenses are often found on small coral or limestone islands and atolls, wh

Lens

(Digital cameras and photo printers) Transparent glass or plastic that has been formed and polished to form a certain shape, usually spherical. When a beam of light reaches the area between the air and the lens, a part of this light is always reflected. The remaining light passes into the lens and alters its propagation direction, i.e. the light i

Lens

In a real camera, a lens is a curved piece of glass or other transparent material that focuses light onto the film. Modern 3D software is capable of simulating a variety of optical distortions created by imperfections in real-world lenses, adding realism to the rendered output.

Lens

Lens: The transparent structure inside the eye that focuses light rays onto the retina (the nerve layer that lines the back of the eye, senses light and creates impulses that go through the optic nerve to the brain). The lens was named after the lentil bean because it resembled it in shape and size. Aside from the lens, the eye has a number of othe

Lens

A optical device made of glass or other transparent material that forms images by bending and focusing rays of light. A lens made of a single piece of glass cannot produce very sharp or exact images, so camera lenses are made up of a number of glass 'elements' that cancel out each other's weakness and work together to give a sharp true image.
