If dot measuring work is processing at a quite long work distance, it is far more enough than formal hand reaching, however, it would be a quite efficient job for users to operate a high density beam emitting tool of a 445nm blue dot laser module. It is always used for those of industrial and high tech precise dot measuring work fields. When it gets basic use of cooling system and proper size tube diameter design, after its easy connects with external electric power source supply, this direct diode emission made 445nm blue laser alignment just makes sure of easy reaching, good direction and high stability blue dot indication for all raw material processing works constantly.

The usual dot alignment work with a 445nm blue dot laser module would be working for a quite long time, it should be working with even more stable performance than formally used laser pointer. It emits similar blue laser beam and blue laser dot as a laser pointer pen, however, it has just got good thermal emitting system. The special use of an import 445nm blue laser diode and metal heat sink cooling system are cooperating well, after configuration with a durable anodized aluminum alloy housing tube, this 445nm blue laser alignment just enables quite easy carrying, good thermal emitting and thermal conductivity in continuous use.

When 445nm blue dot laser module applies a qualified glass coated lens in front of laser beam aperture, cooperating with a glass window, it is bearing any harsh occasion of moisture or dust. Under operation of high density and high transmittance blue laser beam emission at several miles far away, unless it is pointing under sunlight, this blue dot laser alignment up to 50mW to 100mW enables highly precise dot indication within the maximum work distance of 25 meters and other high lighting occasion as well.

According to the advanced use of APC, ACC driving circuit board design, within wide range output power of 50mW to 100mW, this 445nm blue dot laser module keeps work with output power and electric current supply. It enables long lasting dot projection and reduced possibility of tube burning out or damage in continuous use. Whenever users are aware of powerful blue laser radiation and thermal energy hurt to eyes, after proper wearing of 445nm wavelength preventing laser safety goggles, this blue alignment laser just makes easy, secured and no mistake use for all working occasions effectively. 

When dot indication work is processing at different work distances and multiple lighting occasions, it should be a quite nice job for users to operate a high density beam emitting tool of a 515nm green laser diode module. It emits highly visible and bright forest green laser beam emission from an inner 515nm green laser diode. In those of industrial and high tech precise machinery processing work fields, on the basis of its correct use of output power and proper mounting onto any other industrial machine or device, this direct diode emission made 515nm green dot laser just assures ultra clear and bright forest green dot indication for all machinery processing works constantly.
The basic use of a 515nm green laser diode module is always working well for all raw material processing works. It applies an import 515nm green laser diode within 5mW to 50mW as its beam emitting source. Comparing with a simple green laser pointer, it is able to work for longer time and longer distance lasting dot measuring works. As a result, from the very beginning design of this dot laser alignment tool, it has been equipped with a metal heat sink cooling system inside a highly durable anodized aluminum alloy housing tube. It is working well with excellent thermal emitting and thermal stabilization, and maintaining its ultra clear and stable forest green dot projection within long lasting work time of 10 hours per day. 
Owing to its unique use of a qualified glass coated lens and glass window inside a high duration metal housing tube, any time this 515nm green laser diode module is operating under those of moisture, dust, rain or water etc, it still gets perfect protection of itself, and maintains its ultra clear and stable green dot projection for both of long lasting and long distance use. It is working well with high transmittance and high density forest green laser beam emission from inner laser diode. At the same time, no matter it is pointing at close or long distance, this 515nm green dot laser is also working well with ultra clear and precise forest green dot alignment at long extending distance. It is able to instruct users to make clear dot indication for industrial dot alignment, laser medical treatment, bio medical, lab experiment and high tech work etc.
According to quite easy use of APC, ACC driving circuit board, any time 515nm green laser diode module is used for both of long time and long lasting use, it still maintains ultra stable and reliable green dot projection, without any appearance of laser light decay or blur in continuous use. It gets reduced possibility of tube burning out or damage, and achieves ultra long serving lifetime of more than 8,000 hours in proper use. Whenever green alignment laser is operating with high power up to 50mW for long distance and high lighting dot alignment work, it is a key issue to pay high attention to thermal energy hurt to eyes and wear correct laser safety glasses until achieving easy and secured dot measurement perfectly.
