Product Description
Optical lens is a transmissive optical device that affects the focus of a light beam through refraction. A simple lens consists of a single piece of material, while a compound lens consists of several simple lenses (elements), usually along a common axis. Lenses are made from transparent materials such as glass, ground and polished to a desired shape. A lens can focus light to form an image, unlike a prism, which refracts light without focusing.We supply optical lens for optical instrument.Main optical lenses include optical cylindrical lens,optical spherical lens,optical aspherical lens,optical prism,optical filter lens,optical grating,optical windows,optical mirror,optical components,camera lens,fisheye lens,wide angle lens,telephoto lens,projector lens,adapter ring,adapter tube,custom lens,OEM etc..

For example, laboratory glassware, lighting applications, solar thermal systems and pharmaceutical packaging to name the largest.
