No matter what kind of working surface users are trying to make highly precise dot alignment, it might not be easy to reach with simple green laser pointer, but making good job with a Berlinlasers 532nm green laser diode module. It projects the most visible and the brightest green laser light from a 532nm green DPSS laser system.
After easy use of a 5V, 9V 1000mA DC power supply and accepting wide range electric current of 100V to 240V, green laser diode module is applying for multiple application fields. It generates the most visible and the most precise green reference dot within the maximum work distance of 25 meters. Not limited by manual labor force input, it makes good job for drilling system, laser marking, laser engraving, and scientific experiment etc.
