Whenever users are in need of a high speed and high accuracy dot alignment at quite long work distance, it is just a very nice choice for users to have a try of Berlinlasers green laser diode module. it is keeping super low laser beam divergence of no more than 1mard, thus green laser dot is able to keep the smallest size of laser dot diameter in use. In addition, owing to its easily absorbed green color laser light to human eyes, this green laser module is able to get clear and no mistake dot alignment at long distance and high lighting occasion, allowing maximum dot targeting distance of 25 meters in use.
This green laser diode module is very easy to operate, only after its simple connection with DC input power supply, it can support its maximum output power of 100mw. Unless direct laser dot targeting under sunlight it is being used, any power laser module can easily make a clear and quick laser dot targeting on desired working surface precisely and clearly. Users can also make free choice of output power and get easy and no mistake dot aligning all the time.
