In process of highly precise and fine enough line alignment at quite long work distance, it is always making good job with an intense beam Berlinlasers 445nm blue laser line generator. It gets high power up to 50mW to 100mW. Cooperating with a metal heat sink cooling system and 16mm diameter metal housing tube, it enables easy installation and highly stable blue line alignment in continuous use.
This blue line laser module enables wide fan angles of 10 to 110 degree from a glass coated lens. It generates high linear quality and high straightness blue line within 0.5 meter to 6 meters. It should be working with basic learning of line length, line fineness and work distance, only after correct use of output power and optic lens degree, within freely installed distance of 3 meters, it makes sure of easy reaching and no mistake alignment for laser cutting, sand milling, lumber machine, high tech and lab experiment work etc.
