In order to get ideal dot alignment at different work distances, it makes a good job with a direct diode emission made Berlinlasers 515nm green laser diode module. In those of industrial precise dot measuring work, within wide range output power of 5mW to 50mW, it is not only used for close distance and inner room, but also makes ultra clear forest green dot alignment at great distance.
This laser diode module applies 5V, 9V 1000mA DC power supply, it leaves larger space for tube cooling down and enables ultra stable green dot projection in continuous use. Within daily operating time of 8 to 10 hours per day, after correct use of output power and freely adjusted laser beam focus, it gets high quality green laser light source and ultra clear forest green dot alignment for all precise device manufacturing works effectively. 
Applications: drilling system, laser marking, laser engraving, optical instrument, military targeting and high tech
