Powell lenses is one kind of optical ruling lens,Xi'an Lingyue Machinery&Electr.LTD.CNsupply powell lenses that divergence angle from 10° to 100°,the standard have 30°\45°\53°\60°\70°\85°\90°.
When 1 mm laser bean get through the Powell lenses,it is optimized transformed a line which is uniform,stability,straight .Lineation by Powell lenses is better than aspheric lensse,as by powell lense can cancelling central hotspot of Gaussian beams and fade-Marginal distribution.
