In order to make precise and quick enough dot measurement onto various working surfaces, it is not easy to reach with a formal manual dot measuring device, such as a blue laser pointer, sticker or other dot indicator etc. At the same time, after continuous technical innovation of 445nm blue laser diode tech, laser tech engineer just develop a quite practically used device of 445nm blue dot laser alignment. It is performing with highly intense infrared laser light emission from beam aperture, but also projecting a highly clear and accurate blue reference dot projection at quite long work distances.
On basis of the use of an external AC/DC adapter, not the same as formal alkaline battery power source, this 445nm blue dot laser alignment is just able to work with continuous blue laser beam and blue reference dot projection from beam aperture. It is employing an import 445nm blue laser diode as beam emitting source, available with high power up to 50mW to 100mW, this blue laser module just begins to work with highly intense and powerful blue laser light emission. It is performing with highly bright and clear blue reference dot projection, unless it is pointing under sunlight, it is also making quite satisfied dot measuring results at great distance of 25 meters and other formal lighting occasion etc.
When 445nm blue dot laser alignment projects blue laser light directly from 445nm blue laser diode, although it is not as bright as a 473nm blue DPSS laser system, it is just adopting quite small size tube diameter of 16mm. It has been enough to get superior nice thermal emitting from its inner metal heat sink cooling system. In addition, according to the use of durable aircraft used aluminum alloy housing tube, within wide range operating temperature, this 445nm blue laser diode module is just performing with highly stable and clear blue dot emission for both long distance and long time use.
On basis of the use of APC, ACC driving circuit board, no matter how long it is lasting for continuous dot measuring works, 445nm blue dot laser alignment is always performing with constant output power and electric current supply. It is getting perfect protection of itself from overheating, reduced possibility of tube burning out or damage. When it makes proper installation and adjustment of both laser beam focus and dot projecting direction correctly, it is making easy and no mistake alignment laser dot projection at long distance. Only if users are aware of any potential thermal energy hurt to human eyes and wearing correct laser safety goggles, high power blue laser just makes safe and easy use perfectly.
