Precise Pointing 445nm Blue Line Laser Alignment If users are looking for an efficient and easy operating line measuring tool, a direct diode emission made Berlinlasers 445nm blue line laser alignment makes easy and quick blue line projection after its connects with a 5V, 9V 1000mA DC power supply. It is applying for those of industrial precise line measuring fields. The special use of a metal heat sink cooling system and APC, ACC driving circuit board are configured with 16mm diameter metal housing tube. Only after its easy installation within maximum distance of 3 meters, it makes easy reaching and highly clear blue line emission for both long lasting and long distance use. In various industrial precise line measuring work fields, blue line laser module is in need to project various line lengths and line finenesses. It should be selecting with correct optic lens degree and output power. Unless it is pointing under sunlight, it makes good job for high precision and high speed measurement for laser show, laser displaying, industrial precise line measurement and high tech work fields etc. https://www.berlinlasers.com/blue-line-laser-alignment
