WebCylindrical lenses can be used to circularize the beam. Consider a laser diode with beam divergence of θ 1 x θ 2 = 10°x 40°. Any attempt to collimate this beam with spherical optics would result in collimation in one direction … WebCollimation of such beam with a single lens makes the beam elliptical. In some operations, a rounded beam cross-section is much more desired than an elliptical shape beam. Usually, the first idea for collimating and circularizing a beam emitted by a semiconductor laser is to use two orthogonally positioned cylindrical lenses. As shown in Fig 3. great wolf lodge flu
