If the genuine line alignment is continuing for quite long time, in order to achieve high accuracy and high efficiency line alignment onto various working surfaces, it is always making good use to adopt Berlinlasers 650nm red line laser module. It emits red laser beam directly from 650nm red laser diode. The basic use of metal heat sink cooling system is configured into 16mm or 26mm diameter tube, this laser line generator just achieves superior nice thermal emitting and super strong industrial stabilization for various line alignment works. The advanced use of glass coated lens has just make 650nm red line laser module work with high quality and high transmittance red laser light emission, and high linear quality red reference line projection in continuous use. It is projecting highly straight red reference line within 0.5 meter to 6 meters. After passing through measurement and experiment of technical data, this red laser line generator allows correct use of output power and glass coated lens. Only if this compact structure made red laser gets proper mounting onto other machine or device, within the maximum installed distance of 3 meters, it makes no mistake and no barrier line alignment in all occasions effectively. Technical data: Item: Berlinlasers 650nm 5mW-100mW red line laser module Laser class: IIIa, IIIb Optic lens: 10-110 degree glass coated lens Line lengths: 0.5 meter to 6 meters Laser tube: 16mm, 26mm diameter aluminum alloy housing tube Applications: laser cutting machine, sand milling, lumber machine, textile garment processing work etc http://www.berlinlasers.com/650nm-red-line-laser-module
