Negative Cylindrical Lenses

Cylindrical lenses with negative focal length expand beam along one coordinate. Typical application for the lenses is beam shaping. Round laser beam can be focused into a line-spot with help of the lens. Anamorphic shape of the image/beam can be realized by using pair of cylindrical lenses, which makes it irreplaceable tool for circularization of diode laser output beams.
