λ/2 Aspheric Lenses

Optical Lenses -- Powell Lenses

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