Different from a formally used 532nm green DPSS laser system, the real use of a 515nm green dot laser alignment always makes longer time lasting dot projection from beam aperture. It applies an import 515nm green laser diode within 5mW to 50mW as beam emitting source. Being made with cooling system and APC, ACC driving circuit board inside different dimension metal housing tube, it keeps work with constant forest green laser beam and green dot projection, and long serving lifetime in proper use. 
This green alignment laser applies 5V, 9V 1000mA AC/DC adapter, which enables long lasting forest green laser beam and green dot projection within 10 hours per day, not effected by increasing temperature and serious electric current impact as well. It keeps work with high density forest green laser emission, after easy adjustment of laser beam focus, it gets increasing accuracy and brightness green dot projection for all industrial machinery processing works effectively.
Applications: industrial device manufacturing, laser marking, laser engraving, drilling system, military targeting, 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. 

Unlike the use of a simple green laser pointer, in order to make continuous dot projection for a lot of raw material processing works, it becomes a better job for engineers or skilled users to operate a 532nm green dot laser alignment. It applies advanced 532nm green DPSS laser system and qualified optic lens inside a highly durable metal housing tube. Any time it gets constant electric power source supply and proper mounting onto any industrial machine or device, either it is pointing at close or long distance, 532nm green laser module enables high brightness green laser light source emission, ultra clear and precise green dot indication for a lot of raw material processing works effectively.

Together with an AC/DC adapter, without spending extra time on alkaline battery change, this 532nm green dot laser alignment is always keeping work with constant green laser beam emission at long extending distance. The adoption of advanced 532nm green DPSS laser tech enables wide range output power of 5mW to 100mW. It is not simply used for temporary dot positioning work. On contrary, after the advanced use of a metal heat sink cooling system inside a durable anodized aluminum alloy housing tube, this 532nm green laser module always gets superior nice thermal emitting and thermal conductivity, and makes ultra stable and clear green dot indication for both of long time and long lasting use.

Cooperating with a qualified glass coated lens, in order to assure its clear and no decay light performance in long lasting use, this 532nm green dot laser alignment also passes through a series of strict laser beam stability test and aging preventing test. It just enables high transmittance and highly powerful green laser beam radiation and ultra clear green dot projection as long as 25 meters. It is working well as an accessory part of other machine or device. Not limited by long distance, or high height, this 532nm green laser module brings users highly clear dot measurement for laser marking, laser engraving, drilling system, scientific experiment and high tech work etc.

Being made with electric wires extension for both of 532nm green dot laser alignment and DC power supply, within freely installed distance of 3 meters, it enables quite easy installation, quick reaching green dot projection in constant use. The unique use of adjustable focus enables immediate green laser light source concentration and conversion of ultra clear and precise green dot projection at long extending distance. For the most important of all, once green alignment laser gets high power up to 50mW to 100mW, only after high attention to laser safety issue and proper wearing of laser safety glasses, it still assures easy, free and no danger use effectively.
