Not the same as a simple green laser pointer only used for temporary dot positioning work, Berlinlasers 515nm green dot laser alignment just assures constant forest green laser beam emission and green dot projection from beam aperture. It applies import 515nm green laser diode and metal heat sink inside metal housing tube. It projects highly intense forest green laser beam, and highly clear and stable forest green dot projection for both long distance and long lasting use.
This 515nm green laser module adopts qualified glass coated lens, and up to 24 hours aging preventing and beam stability tests. It assures no laser light blur or dim, but projects highly clear forest green dot projection at various work distances. Only if it makes correct use of output power and proper adjustment of dot diameter, it assures low price, good direction and high accuracy dot measurement for industrial precise dot measurement, drilling system, laser engraving machine, military dot positioning and high tech etc.
