On the basis of advanced 445nm blue laser diode tech and qualified optic lens, it has been created into a quite practically used device of a 445nm blue laser diode module. Employed by an import 445nm blue laser diode within 16mm diameter metal housing tube, cooperating with thermal emitting system, it enables quite easy installation, good thermal stabilization and ultra clear blue dot projection for both of long lasting and long distance use. 
After easy connects with 5V, 9V 1000mA DC power supply, this laser diode module keeps work with constant blue laser beam and blue dot projection at long extending distance. It enables high density blue laser light source emission and ultra clear blue dot projection within 25 meters. Any time it makes correct use of output power and proper installation within 3 meters, it brings users easy reaching, no mistake and no barrier dot indication for all precise device manufacturing works effectively. 
Applications: laser show, laser displaying, laser communication, optical instrument, laser medical imaging, and high tech
