WebCreating Circular Beams. Typically, laser diodes emit elliptical-shaped beams that may be unsuitable for applications that require a collimated, circular laser source. Using two cylinder lenses is a common method to circularize an elliptical beam - the first lens magnifies the minor axis of the laser diode, and the second lens collimates the beam. The curved side … the range spin dryers
