How can 532nm green laser diode module work at different distances?

It should not be a hard job for users to get high precision dot alignment until selecting a quite practically dot measuring tool, such as a 532nm green laser diode module. It projects highly visible and bright green laser light source from a middle wavelength 532nm green DPSS laser system. Owing to its special use of cooling system and constant power source supply, under operation with different dimension and high duration mental house tube design, this 532nm green dot laser has just assured the best quality green laser light source emission and the clearest green dot projection at quite long work distance and highlighting working occasions effectively. 
The usual use of a 532nm green laser diode module has to work for a quite a long time and still maintains its clear and stable performance as expected. It projects the similar green laser beam and green dot as a green laser pointer, however not any longer limited for temporary dot positioning work, it should be working with even longer time dot alignment job. The special use of a metal heat sink cooling system has just configured with a high duration anodized aluminum alloy housing tube, the practical green laser dot emission has just assured excellent thermal emitting and thermal stabilization. Once it makes continuous dot projection within ten hours per day, this 532nm green dot laser is still able to make up to 85% beam stability under proper operation by skilled users or professionals.
According to the easy use of a high quality glass coated Lens inside the high durable anodized aluminum alloy housing tube, owing to its strict laser beam stability test and aging preventing tests up to 24 hours, this 532nm green laser diode module is always working well with excellent laser light cycling use and highly reliable green dot projection in long lasting work. it generates high transmitter green laser light source. Even though it is pointing under those of harsh working occasion, owing to the special use of a glass window in front of the laser beam aperture, this dot laser alignment tool still gets perfect protection of itself. It also gets no effect by moisture or dust at all.
Under operation with special design of APC, ACC driving circuit board design, within wider range output power of 5mW to 100mW, this 532nm green laser diode module is working well with constant output power and electric current supply. There is no effect by increasing temperature and serious electric current impact as well. It just allows long lasting green dot projection within ten hours and long serving lifetime of more than 8000 hours. Only if users are taking laser safety measures and wearing correct laser safety glasses, without any eye exposure to beam aperture, users are just making easy and secured dot indication in all application fields effectively.
