Anytime users are feeling quite difficult to get super clear and accurate line alignment at quite long work distance, none of manual line drawing tool or mechanical line alignment tool is much more effective than the use of high power blue line laser module. When it is project highly bright and visible blue laser beam directly from 445nm blue laser diode, equipped with its high quality glass coated lens, this blue laser module is just keeping high linear quality blue line targeting easily.
This Berlinlasers blue line laser module is not a simple laser beam emitting tool as a blue laser pointer, but a very professional and practical used line alignment tool. Users can make free choice of output power and optic lens degree, getting different laser line length from 0.5 meter to 6 meters in use. The real blue line targeting is non contact, without strict limitation of work distance, height and other working environment. Users should only need to choose blue laser alignment with correct output power and laser lens degree, a proper adjusted laser line module gets high accuracy line alignment for all industrial line aligning and high tech effectively.
