What is the best solution to make easy and clear cross line alignment? If the genuine cross line alignment is processing with Berlinlasers 635nm red cross line laser module, after correct use of an external DC input power supply and basic use of inner thermal emitting system, it is making sure of highly intense red laser beam emission and highly clear red cross line generation with accurate 90 degrees. This 635nm red cross line laser module employs import 635nm red laser diode as beam emitting source. It gets wide range output power of 5mW to 100mW. Owing to basic use of metal heat sink cooling system and APC, ACC driving circuit board, it is preventing any overheating and over current impact, achieving extremely stable cross line alignment and up to 85% beam stability in continuous use. When red laser alignment gets proper use of output power and optic lens, after quite easy adjust of laser beam focus and cross line projecting direction, it achieves the most satisfied cross line alignment for multiple occasions effectively. Technical data: Item: Berlinlasers 635nm red cross line laser module Output power: 5mW-100mW Laser class: IIIa, IIIb Optic lens: 10, 15 and 110 degree glass coated lens Adjustable focus: yes Power source: 5V, 9V 1000mA DC power supply Applications: heat transfer machine, military targeting, laser alignment for screen printing system etc http://www.berlinlasers.com/635nm-red-cross-line-laser-module
