If users are not able to make clear enough dot alignment within quite short time consumption, it is not easy to rely on the use of a simple blue laser pointer or other manual dot projecting tool. At the same time, when laser tech engineer makes constant technical innovation of 445nm blue laser diode tech and qualified glass coated lens, it is just developing into a quite practically used device of 445nm blue dot laser module. It emits highly visible and bright blue laser light directly from a blue laser diode. Only if compact size tube made blue laser gets proper installation and adjustment to correct position, it always makes easy and highly clear blue dot alignment at quite long work distance effectively.
This 445nm blue dot laser module gets constant power source from a 5V, 9V 1000mA DC power supply. In practical dot measuring work field, it just leaves enough space for tube cooling down, but also makes sure of continuous blue laser beam and blue reference dot projection from beam aperture. When it accepting wide range electric current of 100V to 240V, it is always getting super strong environmental stabilization, and making sure of continuous blue laser beam emission at several miles far away. Unless it is pointing under sunlight, high power blue dot laser up to 50mW to 100mW also makes highly clear blue dot alignment within the maximum work distance of 25 meters and other formal lighting working occasions as well.
Any time 445nm 50mW to 100mW blue dot laser module is pointing at quite long work distance, in order to avoid laser light decay or blur, it has just passed through a series of laser beam stability tests. For instance, after super rapid electric current adding test, alternative high and low temperature changing test and up to 24 hours aging preventing test, the genuine use of 445nm blue laser alignment has just assured excellent laser light cycling use, and highly reliable blue reference dot projection within constant work time of 8 to 10 hours per day.
According to the use of APC, ACC driving circuit board, in process of constant dot measuring work fields, this 445nm blue dot laser module just assures constant output power and electric current supply. When there is increasing temperature and serious electric current impact, only if it makes continuous blue alignment laser dot projection, it just gets no tube burning out or damage, and keeps work with highly stable and reliable dot measurement in continuous use. At the same time, after high attention to thermal energy hurt to human eyes and correct wearing of laser safety goggles, high power blue laser still makes easy and safe dot alignment in all application fields perfectly.
