Whenever users are making dot generation with this advanced dot projecting laser alignment, users should also pay special attention to the selection of correct output power and the size of emitting red light spot. According to the correct selection of output power, users can always get bright enough red dot emitting on all working surfaces. At the same time, laser tech professionals will help workers to equip the most suitable DC input power supply operating voltage. While the selecting output power of alignment laser is range from 5mW to 30mW, the operating voltage is always between 3V to 3.6V. However, when the operating output power of this red dot laser alignment is range from 50mW to 100mW, the maximum operating voltage should not exceed 5V. Once the selected voltage is quite higher than required, it might cause easily burn out of 650nm red laser diode and electric circuit board inside the laser tube. Whatever kind of working occasions, laser professionals should always pay more attention to its beam stability and the selection of the most suitable output power. By mounting it on required working places and correct dot positioning directions, this advanced dot generating alignment laser will always bring workers the best dot generation result successfully.
