WebA lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (elements), usually arranged along a common axis.Lenses are made from materials such as glass or plastic and are ground, polished, or … WebSimple method for locating the optical center of a lens This article evaluates an old and little used method, which involves holding a small light in front of the lens and marking the spot where the centers of the images reflected from the front and rear surfaces overlap.

WebWith this background, a lens (or optical system) can actually contain any number and combination of lens elements, mirrors, prisms, rotating polygon scanners, filters, diffraction gratings, holographic elements, and other sorts of optical components. Webthe 3D world in cameras with lenses. Camera lenses have another interesting property: they focus all light rays traveling parallel to the optical axis to one point known as the focal point (Figure 5). The distance between the focal point and the center of the lens is commonly referred to as the focal length f.
