Powell Aspherical Lens

The Powell Lens is one kind of aspheric cylinder lens, which can transform laser beam into a uniform straight laser line.
By using Powell Lens, you will get more even energy distribution along the laser line than using the rod lenses and lenses. They outperform cylindrical lenses that generate Gaussian beam profiles with hot-spot center points and fading edges.
Worldhawk offers standard and customized powell lens.
