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.

(1) Lenses are made from transparent materials such as glass, polymers etc which are ground and polished to a desired shape. A Lens can focus light to form an image.

(2) LED light lenses are available in different shapes like free form, asymmetric and symmetric shapes.

Materials used for manufacturing these lenses are PMMA or PC (poly-carbonate).
