In those of precise dot measuring work fields, this 445nm blue laser diode module applies an external AC/DC adapter. It is projecting similar blue laser beam and blue dot as a blue laser pointer. However, once it is required to make long lasting dot alignment, it has been made with good thermal emitting system. The advanced use of an import 445nm blue laser diode and metal heat sink cooling system are cooperating well, which just enables increasing laser beam stability of at least 40% and long lasting blue dot projection within constant work time of 10 hours per day.
In order to make highly clear and precise dot indication at a quite long work distance, this 445nm blue laser diode module applies a qualified glass coated lens and glass window. It keeps work with high density blue laser light source emission at several miles far away. In addition, even though it makes dot indication within the greatest work distance of 25 meters, after correct use of output power, this charming light emitting 445nm blue dot laser just brings users quite special dot aligning source for laser show, laser displaying, laser communication, optical instrument and spectrum analysis etc.
After the adoption of APC, ACC driving circuit board, within wide range output power of 50mW to 100mW, this 445nm blue laser diode module is performing well with constant blue laser beam and blue dot indication in long lasting use. It gets reduced possibility of tube burning out or damage, and achieves long lifetime of more than 8,000 hours. Whenever it gets proper installation onto those of machine or device, only after high attention to any powerful thermal energy hurt and proper wearing of laser safety goggles, users are able to get ideal dot aligning accuracy for all working occasions effectively.
