Lenses are available in fan angles of 30°,45°, 60° and 90°. The optical line generator lens is optimized for a 1.0~1.5mm input laser beam diameter and 2.0~2.5mm input laser beam. 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.
