When users are trying to make dot alignment at quite long work distance, it is always a quite hard work for users to get ideal dot aligning accuracy before selecting a proper device. Instead of the use of simple laser pointer, sticker, or own finger, more and more users are beginning to use high brightness blue laser diode module. Owing to its quite bright blue laser beam emission from high power 445nm blue laser diode, this dot laser alignment is just able to work with extremely bright and visible blue reference dot targeting at quite long distance.
The desired use of blue laser diode module is not the same as a laser pointer. Although it is keeping similar laser light as blue laser pen, however, in order to get constant dot alignment, it is just giving up the use of simple alkaline battery power, but adopting DC input power supply. The external 3V electric power source is supporting blue laser module to work continuously, thus there is no need to make power change during dot aligning use. In addition, this external electric power source also makes dot laser alignment workable under quite harsh working occasion, such as strong interference or strong static.
Within quite high power range of 50mW to 100mW, blue laser diode module is keeping super bright and visible dot targeting in use. When laser tech engineers are paying high attention to its beam stability in long term use, it is just adopting metal heat sink cooling system, which is just making perfect configuration with its aluminum alloy housing and copper raw material made laser diode. Owing to its superior thermal conductivity design, only if it is getting connection with DC input power supply, this dot laser alignment is just able to get nice thermal emitting, and then obtain super stable dot alignment all the time.
In order to get quite nice dot alignment, besides its dual directions cooling design, this blue laser diode module is also getting the most import designed APC driving circuit board. With the super rapid temperature increasing of laser tube, the intelligent feedback system just assures constant output power and electric current supply, thus always getting constant and high stability blue alignment laser dot targeting in long term. When users are avoid eye exposure to powerful blue laser light and remembering to wear a pair of laser safety goggles, this high power blue laser module just assures high security dot alignment all the time.
