An optical lens is a single, optically transparent device shaped/designed to allow the transmission and refraction of light to create a specific and controlled optical outcome. An optical lens is distinct from a photographic lens. The latter integrates both mixed lens elements and various mechanisms to create a complex optical unit for photography.

Coating the lens is the final step in our manufacturing process. An antireflective coating maximizes the energy of light transmitted through the lens. For example, the transmission for two uncoated surfaces of glass (single element) is about 90% (for Nd = ). When the two airtoglass surfaces are singlelayer coated, the transmission
