When blue laser diodes module is getting correct equipment of DC input power supply, it is just keeping high brightness blue laser dot projection with reliable beam brightness on all targeting surfaces. Owing to its high output power blue laser diodes with higher power from 50mw to 100mw, the real alignment with blue laser module is just workable at very long distance. At the same time, only if it is getting 4.2V DC input power supply, it can easily achieve bright enough blue laser dot projection rapidly.
Only if blue laser diode module is equipped with APC driving circuit and metal heat sink cooling system, it can support highly stable dot alignment more than 8 hours. Users should only pay attention to powerful blue laser light, it just get the most secured dot projection perfectly.
