In order to get the most satisfied cross line measuring results on multiple raw material surfaces, it is the greatest choice for user to operate Berlinlasers green cross laser alignment. It is very easy to operate after connect with DC input power supply. It is getting selected output power of 5mW to 100mW, supported by 3V or 9V DC power source and perfect thermal emitting system, this cross line laser is getting superior nice thermal conductivity and the most stable green cross line projection in continuous work. Designed with qualified glass coated lens with 10, 15 and 110 degree, Berlinlasers green cross laser alignment is achieving different dimension cross line source in use. It is getting perfect thermal emitting system, equipped with APC, ACC driving circuit board, it is preventing serious increasing tube temperature and serious electric current impacting, and then achieving highly stable and reliable green cross line targeting in use. Only if this cross line laser module is selected with correct output power and optic lens degree, within the maximum distance of 25 meters, it makes no mistake cross line generation for any lab experiment, scientific research and industrial precise device manufacturing works etc. http://www.berlinlasers.com/alignment-laser/532nm-green-cross-projecting-laser-alignment
