What is the most efficient solution for users to get highly clear and accurate cross line alignment at quite long work distance? Formal cross line printing work is only used for quite close distance, while not able to avoid mistake caused by manual operation. After professional use of Berlinlasers green cross line laser module and quite easy connects with an external DC input power supply, it is keeping work with continuous green vertical and horizontal lines generation with accurate 90 degrees in distance effectively. This green cross line laser module enables quite easy measurement after correct adjustment of laser beam focus and cross line targeting direction. It is used as an accessory part, within freely installed distance of 0.3 meter to 3 meters, it is easy to be installed on any industrial machine or device, and also ensuring no decay light green cross line projection within the maximum work distance of 25 meters. This industrial stabilized green cross laser gets the most satisfied measuring result for laser alignment for screen printing, heat transfer machine, laser medical therapy and scientific research works etc. http://www.berlinlasers.com/532nm-green-cross-line-laser-module
