A photographic lens (also known as 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 or electronically.

This video has uploaded by crashoran show how camera lenses are made, but given that it is PMA season, we figured you ability appetite to booty a attending at this video illustrating how camera lenses are made. There aren’t any sex scenes (thank God) or explosions, but it is absolutely air-conditioned and educational. Two words that are not commonly used in the same sentence. [gizmodo]

A lens is an optical device with perfect or approximate axial symmetry which transmits and refracts light, concentrating or diverging the beam. A simple lens is a lens consisting of a single optical element. A compound lens is an array of simple lenses (elements) with a common axis; the use of multiple elements allows more optical aberrations to be corrected than is possible with a single element. Manufactured lenses are typically made of glass or transparent plastic. Elements which refract electromagnetic radiation outside the visual spectrum are also called lenses: for instance, a microwave lens can be made from paraffin wax. [source:wiki]
