Lenses can be used to focus light
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 and polished or moulded to a desired shape. A lens can focus light to form an image, unlike a prism, which refracts light without focusing. Devices that similarly focus or disperse waves and radiation other than visible light are also called lenses, such as microwave lenses, electron lenses, acoustic lenses, or explosive lenses
We have over 40 spherical processing machines, including hem and oblique axis polishing machine, could make allsizes of spherical lenses, diameter from 0.8mm to 200mm, including planoconvex, bi-convex, plano concave, bi-concave, meniscus, glued achromaticcal lenses
Our aspherical lens Main material is borosilicate glass,compression molding, widely used in lighting device.
