Whatever kind of working surface users are trying to make clear and accurate dot projection, either close or long distance, it makes good job with an Economy red dot laser alignment within 5mW to 100mW. It applies an import 650nm red laser diode within 5mW to 100mW as beam emitting source. After easy use of 5V, 9V 1000mA DC power supply, it gets no relying on manual labor force input, and makes sure of long lasting dot emission in continuous use. 
This red laser module gets ultra compact 16mm and 26mm diameter metal housing tube design. Together with electric wires, it enables freely installed distance of 3 meters, easy and quick reaching of red dot projection onto any raw material surface. After its correct use of output power and easy mounting onto industrial device, it assures the most convenient and the most precise red dot projection for all occasions effectively.
Applications: industrial precise dot measurement, drilling system, laser marking, laser engraving, red laser sight and high tech work etc
