Negative cylindrical lenses act as plano-concave spherical lenses, except on only one axis. These lenses are used in applications that require one dimensional shaping of a light source. These H-K9L Plano-Concave Cylindrical lenses are available uncoated or with one of three anti-reflection coatings:VIS (400~700nm);NIR (650~1050nm) and SWIR(1000~1650nm),which can reduce the amount of light reflected from each surface of the lens.
