What is the most efficient solution to make highly clear cross line alignment at great distance? It is not helpful at all to adopt any manual or mechanical measuring device, however, the adoption of 50mW red cross line laser module makes it easy and quick to get ideal cross line alignment accuracy easily. It makes use of qualified glass coated lens with different fan angle, generating much more complex laser beam in two perpendicular lines with accurate 90 degrees. After easy connect with 9V DC input power supply, 50mW red cross line laser module keeps work with highly intense red laser beam emission and highly clear cross line projection as long as 25 meters. It gets enough space leaving for tube cooling down, configured with APC, ACC driving circuit board, it gets perfect protection of laser tube from burning out or damage. Within the maximum work distance of 25 meters, after correct selection of optic lens degree and easy adjustment of laser beam focus, it achieves the most satisfied measuring result for all industrial precise device manufacturing works.
