Cylindrical Lens, Plano-Concave, N-BK7, 1 x 0.5 in, -25mm FL,650-1000nm

NIR N-BK7 Plano-Concave Cylindrical Lenses

The CKV025AR.16 Plano-Concave Cylindrical Lens is a 650 to 1000 nm anti-reflection coated, 1 inch (25.4 mm) length by 1/2 inch (12.7 mm) width, N-BK7 plano-concave cylindrical lens with an effective focal length of -25 mm. It is 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.
