A cylindrical lens is a lens which focuses light onto a line instead of a point, as a spherical lens would. The curved face or faces of a cylindrical lens are sections of a cylinder, and focus the image passing through it onto a line parallel to the intersection of the surface of the lens and a plane tangent to it. The lens compresses the image in the direction perpendicular to this line, and leaves it unaltered in the direction parallel to it. Cylindrical lenses are widely used in the telecom applications like WSS, 40G/100G modules and laser applications like pump laser modules.
