When users are trying to make highly clear cross line projection onto various targeting surfaces, it should be quite efficient solution to make advanced use of Berlinlasers green cross laser alignment. It generates sensitive color and easily absorbed green laser light from 532nm green DPSS laser. It gets basic design of inner metal heat sink cooling system and APC, ACC driving circuit board inside durable metal housing tube, this green laser module achieves increasing thermal emitting and highly stable green cross line projection in continuous use. When it gets correct installation and adjustment of both beam focus and cross line targeting direction, it achieves high accuracy and quick response cross line projection for all occasions effectively. http://www.berlinlasers.com/532nm-green-cross-projecting-laser-alignment
