In order to make sure of fine and clear enough line alignment at various work distances, it is operating easy after the use of a 515nm green laser line generator. In various industrial and high tech line positioning work fields, after basic use of import 515nm green laser diode and metal heat sink cooling system, it just gets excellent thermal emitting, and increasing stability green line alignment in long time use. The basic use of glass coated lens assures high linear quality and high fineness green line projection from this glass coated lens green laser line generator. It is projecting different line lengths of 0.5 meter to 6 meters, also getting no laser light decay or blur in continuous use. The advanced use of glass window and up to 24 hours aging preventing test assures excellent laser light cycling use, and highly reliable green line projection. When 515nm green laser module makes correct use of optic lens degree and output power, within freely installed distance of 3 meters, it assures no mistake and no barrier green line alignment in distance perfectly.
