When line alignment is processing continuously, not the same as a simple temporary positioning device of a laser pointer, it should be much different experience to make use of Berlinlasers 635nm red laser line generator. It projects highly pure and bright red laser light from 635nm red laser diode. After perfect use of inner metal heat sink cooling system and APC, ACC driving circuit board inside metal housing, red laser module is just a genuine and industrial stabilized laser line alignment tool, applying for highly stable and clear line alignment in all occasions effectively. This 635nm red laser line generator enables freely selected fan angles to achieve ideal line length and fineness. It selects glass coated lens or separate crystal lens, within 10 degree to 110 degree, it generates different dimension line source onto various targeting surfaces. After proper installation onto desired machine or device, only after very easy screw of adjustable focus optic lens, red line laser enables immediate red laser light concentration and the finest line indication onto all surfaces. Technical data: Item: Berlinlasers 635nm red laser line generator Output power: 5mW-100mW Laser class: IIIa, IIIb Optic lens: 10-110 degree glass coated lens, separate crystal lens Adjustable focus: yes Line length: 0.5 meter-6 meters Line fineness: 0.3mm@10cm, 1mm-2mm@2 meters Applications: textile garment processing, laser cutting, sand milling and lumber machine etc http://www.berlinlasers.com/635nm-glass-lens-red-laser-line-generator
