Basic relying on import 515nm green laser diode, not the same as a formal green laser pointer, 515nm green dot laser alignment gets much better performance in continuous use. After giving up formal alkaline battery power source, after adoption of external DC input power supply, accepting wide range electric current within 100V to 240V, this direct diode emission green laser module keeps work with even more stable and reliable dot projection in continuous use. When there is increasing temperature, however, owing to quite special use of electric wires extension, the genuine green laser dot projection not only gets freely installed distance of 3 meters, but also getting perfect dot aligning performance, not affecting by increasing temperature and over current etc.
This 515nm green dot laser alignment makes advanced use of qualified glass coated lens. Even though the genuine dot projection is processing continuously, either it is pointing at great distance or quite long time, green dot projection gets no appearance of laser light decay or dim in continuous use. Whatever kind of working surface it is pointing, green laser module keeps work with high transmittance green laser beam emission and quite low laser beam divergence. When the front part of glass window is designed, even though dot aligning work is processing under any moisture or dust, it is not affecting at all, but always keeping clear dot projection as long as 25 meters.
Under quite easy screw of adjustable focus optics, 515nm green dot laser alignment makes immediate green laser light concentration and extremely accurate dot projection at quite great distance. In addition, after perfect use of APC, ACC driving circuit board, the intelligent feedback system still protects alignment laser from increasing temperature, without any worrying about green laser module burning out or damage. In formal continuous green reference dot projection within 8 to 10 hours per day, after enough time leaving for tube cooling down, it is always getting perfect laser light cycling use and extremely clear dot positioning result in all industrial dot measuring works.
