WebThe output of a laser diode diverges in an asymmetrical pattern, making collimating the beam a challenge. Cylindrical 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 only, with a diverging or … WebBeam diameter (at the output aperture): 50mm.
