The genuine use of high power blue laser diode module is not the same as a blue laser pointer, which is just being regarded as a very professional dot measuring tool workable for those of industrial machinery processing works. It is getting the best use of import 445nm blue laser diode and external electric power source. Not the same as simple alkaline battery power source, the DC input power supply supported blue laser module is always workable for long term continuous dot targeting work. Only if it is equipped with higher operating voltage of 4.2V DC power source, it can easily obtain continuous and high speed blue laser dot targeting all the time.
The generating blue laser beam from blue laser diode module is only available with moderate laser light brightness. It is not as bright as 473nm blue DPSS laser system, however, I would have to confess that only this high power 445nm blue laser module can be made in such kind of compact structure of 26mm diameter laser tube. It is keeping direct blue laser beam emission from its internal 445nm blue laser diode, however, this blue laser alignment tool is easily keeping quite stable and reliable dot positioning work all the time.
In process of long term dot alignment, this high power blue laser diode module is always keeping stable and bright laser dot targeting. However, once there is no extra time leaving for laser tube cooling down, it might greatly affect serving lifetime of this dot laser alignment tool. In order to maintain stable and reliable dot alignment laser performance, the operation of blue laser diode module is just allowing the maximum operating time of 8 hours to 10 hours a day.
Every time users are operating such kind of powerful blue laser diode module, it should be used by skilled users or professionals. Users should also try to be cautious enough with powerful blue laser light and avoid eye exposure to powerful and intense thermal energy. When users are wearing a pair of laser safety goggles, after very proper adjustment of laser dot targeting direction and laser beam focus, high power blue laser module just brings users the most wonderful dot positioning result perfectly.
