In various precise device manufacturing work fields, after special use of clear and accurate dot measurement, it should be much nice job to apply a 30mW 532nm green dot laser alignment. It projects the brightest green laser beam from 532nm green DPSS laser system. It is an industrial stabilized laser device, only if it makes good use of metal heat sink cooling system and constant power source from DC power supply, this green laser module makes sure of continuous green laser beam and green dot alignment in all occasions. This 30mW green dot laser alignment applies a compact size and durable metal housing tube. Designing with extending electric wires, within the maximum installed distance of 3 meters, it makes easy installation and quick green dot projection onto any vertical or horizontal surface. This green laser module enables quite easy adjustment of laser beam focus and easy dot projecting direction adjustment. Within the maximum work distance of 25 meters and other high lighting occasions, this green laser diode module assures high precision dot measurement for laser marking, laser engraving, lab experiment and other high tech works etc. http://www.berlinlasers.com/532nm-green-dot-projecting-laser-alignment
