If line alignment is processing quickly and precisely, it makes an easy job after the use of Berlinlasers 520nm green line laser module. It is projecting forest green laser beam directly from 520nm green laser diode. In various industrial and high tech line positioning work fields, after its basic use of metal heat sink cooling system and APC driving circuit board inside durable metal housing tube, it is achieving superior nice thermal conductivity, and increasing stability forest green line alignment in continuous use. The special use of separate crystal lens has just made 520nm green line laser module different from formal laser device. It is projecting non Gaussian distribution forest green laser beam and highly fine forest green line in use. No matter it is pointing at close distance or long distance, green line is keeping the same brightness from middle part towards both ends. In any type of precise device manufacturing work fields, after correct use of output power and optic lens degree, this laser line generator achieves the finest line alignment in all application fields effectively. Technical data: Item: Berlinlasers 520nm green line laser module Output power: 5mW-50mW Laser class: IIIa, IIIb Optic lens: 10-93 degree separate crystal lens Line lengths: 0.5 meter to 6 meters Line fineness: 0.3mm@10cm, 1mm-2mm@2 meters Applications: lumber machine, laser cutting, sand milling, textile garment processing and lab experiment etc http://www.berlinlasers.com/uniform-520nm-green-line-laser-module
