Plano-Convex Lens, N-SF11, 50.0 mm Diameter, 50.0 mm EFL, Uncoated

Model SFPX196 is an uncoated, 2 inch (50 mm) diameter, N-SF11 precision plano-convex lens with an effective focal length of 50 mm. It has λ/4 surface irregularity, 40-20 scratch-dig, and is designed to meet the demanding requirements of laser electro-optic applications. It is manufactured from fine annealed optical glass and polished to tight tolerances using master test plates ensures minimum wavefront distortion. Tight surface quality tolerances minimize scatter and unwanted diffraction effects. N-SF11 is an excellent material for most visible and near infrared applications. Its high index and lower F/# values allow for more light collection at a shorter focal distance.
