Abstract
A beam shaping apparatus including an optical lens is provided. The optical lens includes a diverging surface and a cylindrical surface. The diverging surface expands the input laser beam into a uniform line in one plane. The cylindrical surface converges the laser beam in another plane. Therefore, the output laser line has the desired width and the uniform density along its length.
