Comparing with other visible laser devices, this 447nm blue laser diode module is always projecting quite charming and attractive blue laser light from beam aperture. In addition, besides its formal dot alignment in those of industrial precise device manufacturing work fields, it is also making good job with highly clear and accurate blue dot projection for special work fields, including laser show, laser displaying, laser communication, military targeting, and scientific research work etc. Whenever it gets proper use by skilled users or professionals, after constant dot projection within 8 to 10 hours, this blue dot laser has just achieved superior nice performance and no decay light or blur in long time use.
According to the use of an external electric power source, this 447nm blue laser diode module just leaves even larger space for tube cooling down, but also makes sure of continuous blue laser beam emission from beam aperture. It gets freely selected high power up to 50mW, 80mW and 100mW. When it is operating as an industrial dot measuring work, only if it makes constant work within the maximum distance of 25 meters, this dot laser alignment has just provided users quite clear and precise dot measurement onto various working surfaces.
When 447nm blue laser diode module adopts quite small size tube diameter of 16mm, even though it is pointing for quite long time, it still gets superior nice and enough space leaving for thermal emitting, and maintains highly reliable blue reference dot projection in continuous use. In order to get precise enough dot alignment, this blue alignment laser also allows quite easy adjustment of both laser beam focus and blue dot projecting direction, it just brings users the best dot aligning result in all application fields. When users are aware of any thermal energy hurt to human eyes and retina, after correct wearing of laser safety goggles and avoiding eye exposure, it always brings users safe and easy dot alignment in all occasions perfectly.
