Cylindrical Lens, Plano-Concave, N-BK7, 50.8x25.4mm, -100mm FL, Uncoated

Uncoated N-BK7 Plano-Concave Cylindrical Lenses

The CKV100 Plano-Concave Cylindrical Lens is an uncoated, 2 inch (50.8 mm) length by 1 inch (25.4 mm) width, N-BK7 plano-concave cylindrical lens with an effective focal length of -100 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.
