Not relying on any manual labor force input, it should be a much better job to operate a high density beam emitting tool of a blue dot laser alignment. The basic use of an import 445nm blue laser diode gets high power up to 50mW to 100mW. After integration with metal heat sink and APC, ACC driving circuit board inside a 16mm diameter metal housing tube, it enables quite easy carrying, good thermal emitting, ultra stable blue dot projection within long extending distance and long time use.
This blue alignment laser enables easy carrying, and quick response blue dot indication onto any raw material surface. The advanced use of a qualified glass coated lens and glass window are assuring high transmittance blue laser light emission, and efficient conversion of ultra clear and bright blue dot projection within long extending distance of 25 meters. When laser users are obeying basic laser safety issue and avoid eye exposure to laser beam aperture, a correct output power made blue laser makes easy and secured dot measurement for all industrial and high tech fields constantly.
Applications: industrial precise dot measurement, laser show, laser displaying, laser communication, military targeting, lab experiment and high tech

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. 

When users are getting serious need of ultra clear and precise dot indication at different work distances, even though it is far more enough than formal hand reaching, it should be a quite nice beginning for users to operate a high density beam emitting tool of a 445nm blue laser diode module. It gets advance use of an import 445nm blue laser diode and a qualified optic lens inside a highly durable anodized aluminum alloy housing tube. Any time this direct diode emission made 445nm blue dot laser gets proper installation and adjustment to correct position, not any longer relying on any manual labor force input, it brings users quite satisfied dot measuring results for all precise machinery processing works. 
Owing to the special use of a qualified glass coated lens inside a durable metal housing tube, this 445nm blue laser diode module is working well with high transmittance and high density blue laser light source emission at long extending distance. At the same time, after passing through quite strict laser beam stability test and aging preventing test, the real blue dot alignment work gets no effect by increasing temperature and serious electric current impact as well. This 445nm blue dot laser still gets up to 85% laser beam stability under constant work time of 10 hours per day. 
Cooperating with the most durable anodized aluminum alloy housing tube, although it gets high power up to 50mW to 100mW, this direct diode emission made 445nm blue laser diode module still gets ultra compact size tube diameter of 16mm. It enables superior nice thermal emitting and thermal conductivity. In addition, after its cooperation with a metal heat sink cooling system, this direct diode emission made 445nm blue dot laser still gets superior nice thermal emitting and ultra clear and stable blue dot generation for all precise machinery processing works.
Within quite long extending distance and formal lighting working occasions etc, within freely installed distance of 3 meters, this 445nm blue laser diode module enables quite easy carrying, quick reaching and no barrier blue dot projection for multiple raw material processing works. It gets freely adjusted laser beam focus and laser dot emitting direction, thus alignment laser brings users increasing accuracy and brightness dot generation at great distance of 25 meters, and gets wide applications for a lot of labs, institutes and colleges. When users are paying high attention to laser safety issue and wear correct laser safety goggles, it just makes easy and secured dot generation for all machinery processing works.
