In any type of highly precise line projection at a long work distance, it makes a good job with a highly intense beam emitting tool of a Berlinlasers 445nm blue line laser alignment. The adoption of a qualified glass coated lens or separate crystal lens gets wide fan angles of 10 to 110 degree, which projects different line lengths within 0.5 meter to 6 meters. Owing to its proper installation and adjustment of laser line fineness, it makes high level of accuracy line projection at long work distance effectively.
