This 445nm blue dot laser module is trying to make continuous dot alignment, it should have to be made with good thermal stabilization. Designing with 16mm diameter aluminum alloy housing tube, it is enough to make superior nice thermal emitting, and highly stable blue dot projection in continuous use. When it is designing with inner metal heat sink cooling system inside durable aircraft used aluminum alloy housing tube, this dot laser alignment has just achieved superior nice thermal conductivity, and highly stable blue dot projection within wide range operating temperature as well.
Under operation with an external AC/DC adapter, after enough the largest space leaving for tube cooling down, this 445nm 50mW blue dot laser module just achieves the largest space leaving for tube thermal emitting, and increasing stability dot alignment in continuous use. When blue laser alignment is projecting highly visible blue laser beam at several miles, but also generating highly clear blue dot projection as long as 25 meters and other formal lighting working occasions. For the most important of all, designing with extending electric wires for both blue laser and DC power source, it is not only allowing freely installed distance of 3 meters, and highly stable blue dot indication under any increasing temperature and serious electric current impact etc.
Without any affect by any surrounding working environments, 445nm 50mW blue dot laser modules gets the most special use of APC, ACC driving circuit board. It is making perfect protection of tube from any possibility of tube burning out or damage, but just keeping the most reliable dot aligning result within constant use of 8 to 10 hours. Any time this alignment laser makes easy screw of adjustable focus optic lens, after immediate blue laser light concentration, it just achieves the most compact size blue dot projection in distance. At the same time, only after high attention to thermal energy hurt to human eyes, after correct use of 445nm wavelength preventing laser safety goggles, this high power blue dot laser just makes sure of highly secured and quick dot measurement perfectly.
