When users are trying to make highly clear line alignment at much longer work distance than formal hand reaching, it is not helpful at all to adopt manual or mechanical line aligning devices. The advanced use of 650nm 50mW red laser line generator makes great technical innovation of 650nm red laser diode tech. Besides its adoption of import 650nm red laser diode, it is also getting larger space leaving for inner metal heat sink cooling system inside metal housing tube. It gets the most efficient thermal emitting and highly stable red line projection in continuous use. After advanced use of qualified glass coated lens or separate crystal lens, either it is pointing Gaussian beam or non Gaussian distribution red laser light, this 50mW red laser line generator keeps work with high linear quality and high straightness red reference line projection. After basic measurement and experiment, after correct recommendation of optic lens degree, red laser module makes high precision red line projection at great distance effectively. Technical data: Item: Berlinlasers 650nm 50mW red laser line generator Laser class: IIIb Optic lens: 10-110 degree glass coated lens, separate crystal lens Line length: 0.5 meter to 6 meters Applications: laser cutting machine, textile garment processing, sand milling, wood, stone and metal processing etc http://www.berlinlasers.com/650nm-non-gaussian-distribution-red-laser-line-generator
