How can DC power 445nm blue laser diode module work at different distances?

 In process of high level of accuracy and stability dot alignment at various work distances, not easy to reach with simple manual dot projecting work at all, it is making even better job with a high precise device of a 445nm blue laser diode module. It makes long lasting and long distance dot alignment work onto different working surfaces. On the basis of a qualified glass coated lens and good cooling system inside durable metal housing tube, only after its proper installation onto any other industrial device or equipment, this direct diode emission made dot laser alignment just makes sure of the best direction and the most stable blue dot projection at quite long work distances constantly.

Designed with an AC/DC adapter, comparing with a simple blue laser pointer, this direct diode emission made 445nm blue laser diode module is in need to work for a quite long time. Employed by an import 445nm blue laser diode within high power up to 50mW to 100mW and a metal sink cooling system inside durable anodized aluminum alloy housing tube, whatever kind of working surface it is pointing, it is always achieving increasing laser beam stability of at least 40% and highly reliable blue reference dot projection within constant work time of 8 to 10 hours per day.

When 445nm blue laser diode module applies a qualified glass coated lens, after passing through a series of strict laser beam stability test, and aging preventing test up to 24 hours, it is working well with high quality and high transmittance blue laser light emission. Under operation with the maximum work distance of 25 meters, without the use of sunlight, it is able to provide user excellent blue dot alignment source for multiple application fields, including laser show, laser displaying, laser communication, military targeting, optical instrument and high tech work tec. 

Designed with ultra compact and durable 16mm diameter metal housing tube design, within freely installed distance of 3 meters, this 445nm blue laser diode module always makes sure of the most convenient installation and the easiest reaching of blue dot projection in constant use. It enables noncontact, no mistake dot indication for both industrial and high tech precise dot measuring fields. Under operation that users are paying high attention to powerful blue laser radiation and thermal energy hurt to eyes, after correct wearing of laser safety goggles and avoiding eye exposure to laser beam aperture, this industrial alignment laser just brings users easy and secured dot generation in all application fields effectively.
