The time users are in need of continuous dot alignment in those of machinery processing works, it is not workable for users to adopt any type of manual dot measuring tool. However, users can just make the best use of high brightness berlinlasers blue laser diode module, only after its quite easy connecting with electric power source of DC input power supply of 4.2V operating voltage, it is just able to get continuous blue laser dot targeting on all working surfaces effectively.
This blue laser diode module gets perfect equipment of metal heat sink cooling system and APC driving circuit design. It has no appearance of laser light dim or blur under condition of proper use by skilled users. This blue laser dot aligning tool is not only workable for industrial dot measuring work, but also quite nice dot instruction for military targeting, laser displaying, laser show etc.
