If you are fallen into serious need of super accurate dot alignment at quite long work distance, it would never a hard job for users until getting the good use of Berlinlasers green laser diode module. It is keeping super bright green laser beam emission from its 532nm green DPSS laser, once it is getting quite high power range of 50mW to 100mW, this green laser module is able to work with clearly visible green reference dot targeting in distance.
This green laser diode module is adopting larger dimension 26mm diameter tube, which is containing enough space as its metal heat sink cooling system and APC driving circuit board. Equipped with its aluminum alloy housing tube, this dot laser module is getting super nice thermal conductivity, and easily obtaining stable enough green reference dot targeting within 8 to 10 hours a day. When users are installing this green laser module on correct position, it is easily obtaining clear dot alignment for laser marking, military targeting, laser medical treatment and other high tech use etc.
