Powell Lens (Laser Line Generator Lens)

The Powell Lens is one kind of Aspherical lens, which can transform laser beam into a straight laser line. At present our Powell Lens are available in fan angles of 5°, 10°, 15°, 20°, 30°, 45°, 53°, 60°, 70°, 75°, 85°, 90° and 96°. The optical line generator lens is optimized for a Φ0.8mm, Φ1mm, Φ1.25mm, Φ1.5mm, Φ2mm, Φ2.2mm, Φ2.6mm, Φ3mm, Φ3.6mm, Φ4mm, Φ5mm and Φ7mm input laser beam diameter. And it will convert the beam into a uniform, straight line. Using this lens design will result in an impressive, even distribution of energy along the length of the line. These lenses offer excellent overall stability and line quality. They outperform cylindrical lenses that generate Gaussian beam profiles with hot-spot center points and fading edges. originally designed for laser line generators, they are now offered unmounted for a variety of custom applications, including: use in alignment, machine vision systems, construction and process control.
