Once you are trying to make continuous blue dot laser alignment at a quite long work distance, it is just a good job for users to have a try of a 445nm blue laser diode module up to 50mW to 100mW. It gets the advanced use of an import 445nm blue laser diode and qualified glass coated lens inside the durable anodized aluminum alloy housing tube. In practical precise dot measuring work fields, under conditions that users are getting correct basic learning of work distance, lighting occasion, and this 445nm blue dot laser should only be selecting with correct output power and making proper installation onto correct position. It just makes sure of high quality and high density blue laser light emission, and highly clear and precise dot indication at quite long work distance continuously. 
The usual use of a 445nm blue laser diode module has to work for a quite long time while still has to work with stable and reliable performance as expected. The basic use of an import 445nm blue laser diode is working well with increasing laser beam stability of at least 40%. In addition, after cooperation with a metal head sink cooling system inside the durable anodized aluminum alloy housing tube, this direct diode emission made 445nm blue dot laser has just achieved excellent thermal emitting and thermal stabilization. It allows constant blue dot indication within ten hours and still maintains highly reliable and clear diode indication within long extending distance of 25 meters in long lasting use.
Under operation with a qualified glass coated Lens and a glass window after built into a durable anodized aluminum alloy housing tube, whatever kind of working surface it is pointing, this 445nm blue laser diode module is working well with high quality and high transmittance blue laser light source emission. It enables highly clear and precise blue dot indication. at the same time, once it projects quite charming and attractive blue laser light from the beam aperture, this 445nm blue dot laser is not just a simple industrial stabilized dot alignment tool, which is also providing users excellent dot alignment solution for special work fields including laser show, laser communication, laser medical therapy, military targeting and high Tech work, etc.
According to the special use of electric wires extension for both 445nm blue laser diode module and DC power supply, within freely installed distance of three meters, it enables the most convenient installation and the easiest reaching of blue dot source emission onto any raw material surface. It always brings users no mistake long lasting and non contact blue dot projection in continuous use. Under conditions that it makes freely adjusted laser beam focus and dot emitting direction, within freely installed distance of 25 meters and other formal lighting working occasion, it brings users quite satisfied dot measurement as expected. Users should only obey basic laser safety issue, after correct wearing of laser safety goggles and avoid any eye exposure, this alignment laser just brings the users easy and secured dot alignment in long lasting use effectively.
