If users are getting serious need of highly clear and accurate dot alignment at different work distance, not easy to reach with a simple green laser pointer or other manual dot projecting tool, it is the best job for users to apply a high brightness Berlinlasers 532nm green laser diode module. Only if it gets constant power source, after easy use of 5V, 9V 1000mA DC power supply, it is working well with highly visible and clear green dot alignment within the maximum work distance of 25 meters and multiple lighting occasions etc.
Available with wide range output power of 5mW to 100mW, this green laser diode module is projecting highly visible red laser beam at several miles far away. Unless it is pointing under sunlight, it is making good job for highly clear and accurate dot indication for drilling system, laser marking machine, laser engraving machine, high tech and lab experiment etc.
