The CKV513 is an uncoated N-BK7 plano-concave cylindrical lens, with dimensions of 25.4 x 12.7 mm and an effective focal length of -12.7 mm. Designed to meet the demanding requirements of laser electro-optic applications, Newport's N-BK7 precision cylindrical lenses are manufactured from fine annealed optical glass and are polished to tight tolerances to ensure minimum wavefront distortion. They are available either uncoated or multi-layer AR coated, with a choice of broadband coatings or a laser line V-coating for 1064 nm.
