Without worry about dot aligning accuracy, the use of Berlinlasers 515nm green laser diode module is always able to bring users high speed and high accuracy green reference dot targeting on various working surfaces easily and accurately. According to quite easy screw of laser beam aperture part, green laser beam is temporarily focused, and then forming into a small diameter green dot immediately.
Once 515nm green laser module is available with high power 50mW, it should be equipped with higher operating voltage of 8.4V DC input power supply until getting bright enough green reference dot immediately. It is a direct diode emission dot laser alignment tool, equipped with nice metal heat sink cooling system and APC driving circuit board inside its metal housing tube, this green laser module is easily getting stable enough green reference dot targeting in long term use. Only if this green laser dot alignment is properly adjusted with dot targeting direction and laser beam focus, it is making no mistake dot alignment perfectly.
