In order to make highly clear and accurate dot projection at various work distances, a simple green laser pointer is substituted by a high brightness device of Berlinlasers 532nm green laser diode module. It projects highly visible green laser beam from 532nm green DPSS laser system, which is working well with super compact size and bright green dot projection at various work distances.
After easy use of 5V, 9V 1000mA DC power supply, this green dot laser keeps work with constant green laser beam and green dot projection. It gets no effect by increasing temperature and serious electric current impact a well, and no relying on any manual labor force input or prior dot positioning work etc. Within freely installed distance of 3 meters, a correct output power made laser device assures no mistake, no barrier, long lasting dot projection for industrial precise device manufacturing work, lab experiment, high tech, drilling system etc.
