Without the use of quite simple manual cross line drawing device, laser tech engineer is always making quite great technical innovation of a Berlinlasers green cross laser alignment. It is available with wide range output power of 5mW to 100mW, after correct use of 5V, 9V 1000mA DC input power supply, it makes sure of highly intense green laser beam emission and highly clear green vertical and horizontal lines at various distances. When green cross laser alignment is pointing onto different targeting surfaces, it is requiring to generate different dimension cross line source in use. The advanced use of qualified glass coated lens enables freely selected fan angles of 10, 15 and 110 degree. It generates high linear quality and highly straight cross line source, available with different cross line length within 0.5 meter to 6 meters, this green laser module achieves highly precise and accurate cross line alignment for all occasions effectively. Technical data: Item: Berlinlasers 5mW-100mW green cross laser alignment Wavelength: 532nm Laser class: IIIa, IIIb Optic lens: 10, 15 and 110 degree glass coated lens Adjustable focus: yes Power source:L 5V, 9V 1000mA DC input power supply Applications: laser alignment for screen printing system, heat transfer machine, laser medical tech and military cross line positioning etc http://www.berlinlasers.com/532nm-green-cross-projecting-laser-alignment
