The special use of glass coated lens has just assured high quality green laser light source emission. This 515nm green dot laser alignment is performing well with high transmittance green laser light emission. Every time it passes through quite strict laser beam stability tests, including super rapid electric current adding test, alternative high and low temperature changing test and up to 24 hours aging preventing test, only if it makes constant green dot projection within 8 to 10 hours per day, this direct diode emission made 515nm green laser module has just assured highly clear green dot projection, and no decay light emission for both long time and long distance use.
According to the use of an external AC/DC adapter, the usual use of 515nm green dot laser alignment is projecting highly visible forest green laser beam at several miles far away. Even though it gets high thermal consumption, only after its correct use of a 9V 1000mA DC power supply and larger size tube diameter of 26mm diameter aluminum alloy housing tube, this direct diode emission made device of 515nm green laser module has just assured superior nice thermal conductivity, and highly reliable forest green dot projection within wide range operating temperature as well.
Without any serious relying on manual labor force input, 515nm 50mW green dot laser alignment is operating easy and quick. It is projecting a noncontact and no barrier forest green laser dot, without the use of sunlight, it always makes quite satisfied forest green dot projection at long work distance of 25 meters and other formal lighting working occasions as well. When green alignment laser makes easy screw of adjustable focus optic lens and high speed forest green laser light concentration, it just gets increasing accuracy forest green dot projection at long distance easily. Any time users are aware of any thermal energy hurt to human eyes, after correct wearing of laser safety glasses, it assures no danger and no mistake dot alignment in all occasions perfectly.
