... 45°, 53°, 60°, 70°, 75°, 85°, 90° and 96°. The optical line generator lens is optimized for a Φ0.8mm, Φ1mm, Φ1 ... laser beam diameter. And it will convert the beam into a uniform, straight line. Using this lens design will result in ... impressive, even distribution of energy along the length of the line. These lenses offer excellent overall stability and line quality. They outperform cylindrical lenses ...
