When laser tech engineer is paying high attention to develop practically used laser device, such as a high power 445nm blue laser diode module, it would make sure of quite easy and accurate blue reference dot projection in distance. It is employing import 445nm blue laser diode as its beam emitting source and constant power source from DC input power supply. Beginning with high power up to 150mW to 500mW, and separate thermal emitting system, this high power blue dot laser would make sure of highly clear and improving stability blue reference dot projection in distance effectively.
This high power 445nm blue laser diode module emits blue laser light directly from 445nm blue laser diode. It is getting much longer wavelength than 473nm blue DPSS laser, however, it is able to be made with quite small size tube diameter and still keeping work with more stable and reliable blue reference dot projection in continuous work. When 445nm blue laser diode gets mass production, after production into a laser dot alignment tool, it is not only keeping quite nice laser light cycling use, but also available with quite low price. When it is generating quite charming blue laser light from beam aperture, besides it is used for industrial precise device manufacturing work, but also getting quite satisfied dot generation for laser show, laser communication, military targeting and laser displaying works etc.
Without any relying on manual labor force input, only after quite easy connect with a DC input power supply, high power blue laser diode module makes continuous blue reference dot projection immediately. When it is trying to make continuous blue reference dot projection from laser beam aperture, it is also generating thermal energy from laser beam aperture. This dot laser alignment tool gets important design part of APC, ACC driving circuit board. The intelligent feedback system prevents serious electric current impacting and reduces possibility of laser diode and electric driving circuit burning out under rapid temperature increasing of laser module tube.
Under special design part of separate metal heat sink cooling system, high power 445nm blue laser diode module leaves the largest space for thermal emitting and enables long term continuous dot alignment constantly. In occasion that users are requiring high level of stability dot alignment, this alignment laser should be operated within 8 t 10 hours per day. In addition, any type of eye exposure to laser beam aperture might cause serious hurt to human eyes and retina. It is an important issue to wear professional laser safety goggles until achieving easy and free measurement constantly.
