Users are always trying to make highly clear dot alignment at quite long work distance, a simple blue laser pointer cannot easy to reach ideal dot aligning accuracy as expected. The selection of 445nm blue laser diode module just makes easy and constant blue laser beam and blue dot alignment at long work distance. It is operating easy and quick and also getting no barrier of long distance, high height and other hard reaching places etc.
According to real work distance and lighting occasion, after correct use of output power, 445nm blue laser diode module always makes highly clear and accurate blue dot alignment at long work distance. For the most important of all, after its easy adjustment of both laser beam focus and dot emitting direction, within freely installed distance of 3 meters, blue dot laser makes low price, long lasting and high stability dot alignment for all application fields.
