26 Nov 2021 Powell Lenses is an optical line-drawing prism with full fan angles from 1 ° to 120 °. Standard specifications are 5 °, 10 °, 30 °, 45 °, 53 °, 55 °, 60 °, 70 °, 85 °, 90 °, and 110 °. 120 °.
Powell prism can optimally divide the laser beam into a straight line with uniform optical density, good stability and good linearity. The lineation mode is better than that of cylindrical lens, which can eliminate the central hot spot and faded edge distribution of gaussian beam. Gaussian laser beam by ordinary cylindrical lens, produces the uneven distribution of straight line, and Powell at the top of the prism is complex two-dimensional aspheric surface, through laser will produce a large number of spherical aberration, light path is redistributed, reduce the light of the central region, increase the edge of the light, to form a uniform line, suitable for all kinds of biological medicine, automobile assembly, food processing and machine vision applications.
