What does DC power 445nm blue laser diode module work at different distance?

 Whatever kind of working surface users are trying to make extremely clear and accurate dot alignment, it is processing at quite long work distance, thus a lot of factory workers and engineers would prefer to make use of an industrial stabilized device of a 445nm blue laser diode module. It is emitting highly visible and intense blue laser beam directly from a 445nm blue laser diode. According to easy use of an external DC power supply and proper installation onto any other industrial machine or device, this dot laser alignment tool always makes sure of easy reaching, and highly reliable blue reference dot projection for all machinery processing works.
The usual dot alignment with a 445nm blue laser diode module is processing onto different working surfaces, thus it is required to work with different dimension dot alignment in distance. It is applying a high quality glass coated lens. Before it is available on the laser market, it also passes through a series of strict laser beam stability and aging preventing test up to 24 hours. After daily constant blue laser dot alignment within 8 to 10 hours per day, after leaving enough time and space for tube cooling down, it is achieving high level of laser light cycling use and the most reliable blue dot projection for a lot of occasions.
In order to make easy and quick dot alignment onto various working surfaces, this 445nm blue laser diode module applies an external AC/DC adapter as electric power source. Employed by an import 445nm blue laser diode up to 50mW to 100mW, after correct use of 5V, 9V 1000mA DC power supply, it is emitting highly powerful and intense blue laser beam at several miles far away. In practical precise dot measuring work fields, unless it is pointing under sunlight, this blue dot laser always makes sure of the most charming blue laser light emission, and highly precise blue dot indication for all high tech and lab experiment works etc.
According to quite easy use of electric wires for both 445nm blue laser diode module and DC power supply, it always enables the most convenient installation and the easiest reaching of blue dot indication onto any vertical or horizontal surface. It enables no track, no barrier and steady processing of any raw material surface. When alignment laser projects the most powerful blue laser radiation and thermal energy, it might bring users serious thermal energy hurt to eyes. It is a necessity to wear correct laser safety goggles and avoid eye exposure to laser beam aperture so as to achieve easy and secured dot measurement in long lasting use.
