optical lenses includes spherical, achromatic, aspheric, Powell, and cylindrical lenses, and are offered with or without antireflection coatings deposited on their surfaces
Optical lenses can be made in many shapes and may be comprised of a single element or form constituent parts of a multi-element compound lens system. They are used to focus light and images, produce magnification, correct optical aberrations and for projection, mainly controlling the focus or divergence light used in instrumentation, microscopy and laser applications.Any specification of convex or concave lens can be produced according to required transmission and material, to a specific focal length.
Coatings: Includes anti-reflective, scratch-resistant, anti-fog, and ultraviolet (UV) blocking layers
