When users are trying to make highly clear dot alignment at close distance, it is not easy to reach with a simple green laser pointer, but making efficient job with a 5mW green laser diode module. It projects the most sensitive color and the easily absorbed green laser light, and less than 1mrad laser beam mode. It is working well with the most compact size green dot diameter of 0.3mm at 10cam, and 1mm to 2mm dot diameter at 2 meters work distance. Every time 16mm diameter tube made green laser gets proper installation and adjustment of both laser beam focus and green dot projecting direction within three dimensions, it assures the lowest price and the most stable green dot alignment for industrial and high tech precise dot measuring work fields effectively.
