Introduction of Cylindrical Lens used in optical instruments

A cylindrical lens is a lens which focuses light into 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 into a line
parallel to the intersection of the surface of the lens and a plane tangent to it.
