Optical Lenses
Optical Lenses transmit light using refraction and can focus light to form an image, unlike a prism that will refract light but not focus it. In it’s simplest form it’s a single piece of transparent material made from glass or plastic that’s moulded and polished into the desired shape. The surface of the lens is either convex, concave or flat. Some more complex lenses will consist of multiple rather than single elements. The types of lens available include Plano-Convex or double Convex, Plano-Concave or Double Concave, Aspheric, Achromatic, Germanium, Silicon, Zinc Selenide and Fused Silica. Perhaps the most common use for Optical lenses is in the production of eyeglasses, a and contact lenses to correct visual impairments, but lenses are also used in a variety of imaging systems too, including; photography equipment such as cameras, projectors, microscopes and telescopes. They are also used in a variety of other industries too including industrial, defence and life sciences.
