If you are not able to work with extremely accurate line alignment without quite short time, anyway, it is just the good chance for users to make good use of Berlinlasers green line laser module. It is keeping highly straight and high linear quality green reference line targeting from laser beam aperture part. Users should only make easy installation of green laser module on desired machine or instrument, and then getting the clearest line instruction on any vertical or horizontal surface effectively.
Green line laser module gets selectable optic lens degree from 10 degree to 110 degree from glass coated lens. When it is properly selected with its output power and optic lens degree, it is obtaining the clearest line instruction on any vertical or horizontal surface effectively. Green line targeting is workable for wide range distance of 25 meters. Within wide range line length from 0.5 meter to 6 meters, a correct power and lens degree made green laser module is just making sure of the best line alignment for laser cutting machine, laser car wheel alignment system, wood milling and sand mill etc.
