The KBX067AR.16 N-BK7 Bi-Convex Lens is a 1 inch (25.4 mm) diameter, 650 to 1000 nm anti-reflection coated, N-BK7 bi-convex lens with an effective focal length of 125 mm. It is designed to meet the demanding requirements of laser electro-optic applications. Newport's N-BK7 precision bi-convex lenses are manufactured from fine annealed optical glass and are polished to tight tolerances using master test plates to ensure minimum wavefront distortion.
