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

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. 

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
