China VY Optics High Quality Laser Line Generator Lens Powell Lenses
Item Number:X-P23B9X10101
Powell Lenses, or powell prism, also known as Laser Line Generator Lenses, convert laser beams into uniform, straight lines. Comparing with cylindrical lenses, the laser line generator lenses has an advantage because latter one produces a poorly illuminated line, limited by the non-uniform Gaussian laser beam. Huge spherical aberration redistribute light along the line, decreasing the light in the central area while increasing the light intensity at the line's end. The outcome of a Powell lens is uniformly illuminated line used in all forms of machine vision applications.

What is the difference between cylindrical and Powell lenses?
The Powell lens shifts light from the center to the edge of the beam to produce a uniform intensity line, while the cylindrical lens maintains the Gaussian profile of the beam, so its line is much brighter in the center.
