If users are not able to make easy and quick enough dot measurement at quite long work distances, it is not easy to rely on manual labor force input, but making good job with an intense beam emitting tool of 445nm blue laser diode module. It applies qualified 445nm 50mW blue laser diode as beam emitting source. When it is trying to make long lasting dot measuring works, it just gets advanced use of cooling system and glass coated lens. After its proper installation and adjustment to correct position, this blue dot laser always brings users low production cost and good stability blue dot generation in long lasting use.

According to the use of an external AC/DC adapter, owing to its acceptation of wide range electric current of 100V to 240V, this 445nm blue laser diode module is assuring continuous blue laser beam and blue dot emission. It is not as bright as a 473nm blue DPSS laser system. However, once it is getting basic use of an import 445nm blue laser diode and metal heat sink cooling system, this direct diode emission made blue dot laser only adopts quite small size tube diameter of 16mm. It is getting at least 40% improvement of laser beam stability, and highly stable blue reference dot projection within long lasting work time of 8 to 10 hours per day.
On basis of advanced use of a qualified glass coated lens, whatever kind of working surface it is pointing, 50mW 445nm blue laser diode module is working well with high intensity and high transmittance blue laser light emission. For the most important of all, owing to its strict laser beam stability tests and aging preventing test up to 24 hours, it is always working well without laser light decay or blur. Under special working occasion of moisture or dust, the front part of glass window still makes perfect protection o itself, and keeps highly reliable blue reference dot projection in proper use.
With the assistance of a laser alignment mounting bracket and special use of extending electric wires, within the maximum installed distance of 3 meters, 50mW 445nm blue laser diode module just makes sure of the most convenient installation, and the easiest blue dot projection onto any raw material surface. It allows easy and quick response blue dot emission onto any raw material surface. When users are aware of any powerful blue alignment laser radiation and reflection, after correct wearing of laser safety goggles and avoiding eye exposure to beam aperture, it makes sure of easy and free dot alignment in all application fields perfectly.
