Cylindrical lens beam
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 … WebCylindrical Lenses 2X Magnification (AR 400-700 nm) GREEN The optical system for reducing the divergence of the laser beam. Dedicated for BLUE and GREEN beams which have better divergence than RED ones. Lenses have 2 X magnification and the divergence of the beam is also corrected 2 X times. $60.00 PCS Add to cart Lead time: 2 weeks
