In various industrial precise cross line aligning work, this green cross line laser module enables freely selected fan angles of 10, 15 and 110 degree from a qualified glass coated lens. It projects highly straight and fine green cross line within 0.5 meter to 6 meters. After its correct use of output power and optic lens fan angle, it makes high precision cross line alignment at great distance and high lighting occasions perfectly. Applications: laser car wheel alignment, military targeting, laser medical therapy, garment processing and high tech etc https://www.berlinlasers.com/oem-lab-lasers/cross-line-laser-modules https://www.berlinlasers.com/532nm-green-cross-line-laser-module
