Powell lenses are available in fan angle from *0°to **0°.The typical angles are *0°,*5°,*0° and *0°.Each optical line generator lens is optimized for a 0.8mm laser beam diameter and will convert the beam into uniform, straight line. Using the Aspherical Powell-glass 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 which generate Gaussian beam profiles with hot-spot center points and fading edges. Originally designed for laser line generator, they are now offered unmounted for a variety of custom applications, including: alignment, machine version, construction，process control and laser scanning systems. Order information： 1. Full fan angle 2. Diameter and divergence of laser beam 3. Working distance and Line width at working distance 4. Energy uniformity at working distance
