The real line alignment work with a manual line drawing or line printing device is far more enough to avoid mistake caused by manual operation. On contrary, when line alignment is processed by 515nm green laser line generator, it is just generating extremely clear and accurate green laser beam and green reference line at several miles far away. In practical laser line alignment work, in order to avoid laser light decay and make perfect control of real line thickness, this 515nm green laser module should be properly used within maximum work distance of 25 meters.
When 515nm green laser line generator is keeping direct laser beam emission from 515nm green laser diode, available with much shorter wavelength than 532nm green DPSS laser system, it is still able to work with improving laser beam stability of at least 40%. At the same time, from the very beginning design of 515nm green laser diode, it is not allowed to be available separately on the market. When it is being made into a real and practically used dot laser alignment tool, it is not only workable for formal industrial dot aligning work, but also providing quite nice dot aligning solution for scientific research, lab experiment, laser medical treatment work etc.
Not the same as formal visible laser devices, once 515nm green laser diode module is workable with higher output power of 30mW to 50mW, it is taking even higher thermal consumption. It should only be equipped with quite higher operating voltage of 8.4V DC input power supply, and then maintaining highly stable alignment laser dot targeting in long term use. Anytime high intensity green laser beam is generating from laser beam aperture, users should always wear 515nm wavelength preventing laser safety goggles, and then making sure of no danger alignment constantly.
