  6. In geology a lens is a body of ore or rock or a deposit that is thick in the middle and thin at the edges, resembling a convex lens in cross-section. Adjective: "lenticular".
  7. In geometry, a lens is a shape comprising two circular arcs, joined at their endpoints. If the arcs have equal radii, it is called a symmetric lens. The corresponding shape is the lune. The Vesica piscis is one form of a symmetrical lens; the term is also used for lenses generally.
  8. A lens is an optical device with perfect or approximate axial symmetry which transmits and refracts light, converging or diverging the beam. A simple lens consists of a single optical element. ...
  9. Lens is a commune in the Pas-de-Calais department in northern France. It is one of France's large Picarde cities along with Lille, Valenciennes, Amiens, Roubaix, Tourcoing, Arras, and Douai.
  10. A camera lens (also known as photographic lens, objective lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically ...
  11. Lens is a municipality in the district of Sierre in the canton of Valais in Switzerland.
  12.

  15. (Lenses) Most DSLRs have interchangeable lenses – you can take the lens of the front of the camera, and put on a different lens. Lenses are typically either primes (fixed focal lengths) or zooms (variable focal length), and go from extreme wide angles to extreme telephotos.
  16. (Lenses) Pages that are created to focus on specific subjects of interest. At Yaktivate we use Squidoo™, a publishing platform and community, for that purpose.
  17. (Lenses) Prescription or non-prescription devices set in frames.

  23. A circular and transparent glass or plastic piece that has the function of collecting light and focusing it on the sensor to capture the image.
  24. Natural lens of eye; transparent intraocular tissue that helps bring rays of light to focus on the retina.
  25. A transparent optical component consisting of one or more pieces of optical glass with surfaces so curved (usually Spherical), that they serve to converge or diverge the transmitted rays of an object, thus forming a real or virtual image of that object.
