In order to make accurate dot projection on targeted surfaces, users have to choose highly visible 532nm green laser at both close distance and long distance measurement. This kind of green laser diode manufactured alignment laser adopts the most advanced design of external designed DC input power supply to provide enough electric power to make it provide continuous dot projection efficiently. According to the exact output power of green laser alignment, users will be recommended the most suitable pointing voltage so as to emit bright enough green reference dot clearly on required places all the time.
The selectable output power of green laser alignment is ranging from 5mW until 100mW. Usually 5mW to 30mW laser alignments uses 3.6V operating power supply, and high powered lasers within output power between 50mW and 100mW will need to adopt higher operating voltage of 4V so as to project bright enough green reference dot on targeted surfaces accurately. At the same time, this dot projecting laser alignment is always being designed with different size of laser tube of diameter 16mm and 26mm. Low powered laser alignment always requires to be designed with small size laser tube, while high powered lasers require larger size of laser tube with diameter of 26mm.
When users are selecting high powered green dot laser alignment more than 50mW, users should always pay high attention to its safety measures and high stability in continuous dot projection. When it is being used in long time continuous dot projection, its laser tube will become very hot and might easily cause burning out of laser diode. With the constant temperature improving of its inner laser tube, the electric circuit board is specially designed with intellectual feedback system. This electric circuit board will always make prompt reaction of high temperature laser diode and then protect its laser diode in the best working condition. In addition, it is just equipped with qualified metal heat sink thermal stabilization control system. This special configuration has just made this alignment laser working stable and reliable constantly and promptly.
