If there is not a quite nice method for users to get clear enough line alignment in distance, none of manual line drawing tool can be workable as nice as a Berlinlasers green laser line generator. This is a professional line alignment tool, only according to its free selection of optic lens degree from 10 degree to 110 degree, this glass coated lens made green laser module just achieves different line length, and then fulfilling the clearest line instruction for multiple industrial and high tech line aligning use fields marvelously.

Owing to its nice use of metal heat sink cooling system inside its metal housing tube, this green laser line generator gets quite nice thermal conductivity, and also bearing harsh occasion under mechanical shocking, calibration or moving etc. Users can install this green laser module on any other industrial machine or device, and then getting the clearest laser dot instruction on any vertical or horizontal surfaces effectively. Users should also be cautious enough with powerful green laser light and thermal energy, a correct power made green laser module just gets no danger and no mistake line alignment perfectly.
