Have you ever fallen into serious need of highly clear and fine cross line alignment? No matter it is pointing at close or long distance, it is not any longer a hard job after the use of Berlinlasers 635nm red cross line laser module. It employs an import 635nm red laser diode within 5mW to 100mW, equipping with good cooling system and durable metal housing tube, it gets strong industrial stabilization, and increasing stability red cross line alignment constantly. The special use of glass coated lens assures high quality red laser light emission, and high linear quality red cross line projection with different dimensions. It is performing with highly straight and accurate two perpendicular lines with accurate 90 degrees, but also generating various cross line lengths within 0.5 meter to 6 meters. When this compact size tube made red laser gets proper installation and adjustment of laser beam focus, it makes sure of the finest cross line alignment for all application fields perfectly. 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 Tube diameter: 16mm, 26mm aluminum alloy housing tube Applications: laser alignment for screen printing, heat transfer machine, military targeting and lab experiment etc http://www.berlinlasers.com/635nm-red-cross-line-laser-module
