The KPC019AR.16 N-BK7 Plano-Concave Lens is a 650 to 1000 nm anti-reflection coated, 12.7 mm diameter, N-BK7, plano-concave lens with an effective focal length of -75 mm. It is designed to meet the demanding requirements of laser electro-optic applications. Newport's N-BK7 precision plano-concave lenses are manufactured from fine annealed optical glass and are polished to tight tolerances using master test plates to ensure minimum wavefront distortion.
