from CeNing Optics Co., Ltd.
A Powell lens is used to generate a straight line with aspherical curvature on its apex, thereby outputting a line that has an even distribution of energy. For comparison, cylindrical lenses generate Gaussian beam profiles with hot-spot center points and fading edges. The uniformity of the output... [See More]
