In order to make highly stable and reliable dot alignment at quite long work distance and long time use, it makes good job with an intense beam 445nm blue laser diode module. It projects formal brightness blue laser light directly from a 445nm blue laser diode up to 50mW to 100mW. Only after its good use of cooling system and APC, ACC driving circuit board, it is achieving superior nice thermal emitting and the most stable blue dot alignment within long lasting time of 8 to 10 hours. This blue dot laser should only be selecting with correct output power and easy mounting onto industrial device. It is not only projecting quite charming and attractive blue laser light, but also brings users high precision dot alignment for laser show, laser displaying, laser decoration, laser communication, high tech and lab experiment work etc.
