What is the best solution for users to make highly clear dot measurement? It might be processing at quite long work distance, although it is not easy to reach with a simple blue laser pointer or other manual dot projecting tool, however, it still makes good job for users to apply a direct diode emission made device of 445nm blue laser diode module. It keeps work with formal brightness and intense blue laser light emission directly from a 445nm blue laser diode. In various industrial and high tech precise dot measuring work fields, after its proper installation and freely adjusted laser beam focus, it always assures easy reaching and long lasting blue dot indication at long work distance constantly.
The usual use of 445nm blue laser diode module is always continuing for quite long time. Not spending extra time on alkaline battery power change, after the use of a 5V, 9V 1000mA AC/DC adapter, it is always keeping work with constant blue laser beam emission at several miles far away. It should be working without sunlight. When it gets wide range output power of 50mW to 100mW, after projection of highly visible blue laser beam emission at several miles far away, this blue dot laser alignment also makes sure of highly clear blue dot indication within the maximum work distance of 25 meters and other formal lighting working occasions etc. 
No matter dot measuring work is processing for long time and long distance, this 445nm blue laser diode module should be working with highly stable and no decay light blue dot indication in long lasting use. It is applying qualified glass coated lens. In order to avoid any appearance of laser light decay or blur, it just passes through a series of beam stability test, aging preventing test, alternative high and low temperature changing test tec. In addition, when this industrial stabilized blue dot laser alignment is operating by skilled users or professionals, only after its constant dot alignment within 8 to 10 hours per day, it just achieves excellent laser light cycling use, and highly reliable blue dot projection for all raw material processing works.
Within wide range installed distance of 3 meters, with the assistance of a laser alignment mounting bracket, this 16mm diameter made 445nm blue laser diode module always assures convenient installation, and easy reaching of blue dot emission onto any vertical or horizontal surface. It is operating easy and conveniently as an accessory part, and making sure of noncontact and long lasting dot indication onto any raw material surface. When blue alignment laser gets freely adjusted laser beam focus and dot emitting direction, after correct wearing of laser safety goggles, it achieves easy and secured blue dot projection for all application fields constantly.
