Blue line laser alignment adopts 445nm blue laser diode as light emitting source, the usually available output power is range from 50mW until 100mW. This 445nm laser wavelength is not the same as 473nm DPSS blue laser, which is more stable and reliable than 473nm blue laser. In addition, the complex 473nm DPSS laser is not able to be manufactured with quite simple pen design, but also in quite high output power. As a result, the output power of 445nm blue laser alignment might not be affected by the operating output power, but always making more stable and reliable line projection on targeted surfaces all the time while comparing with 473nm blue DPSS laser.
Whenever users are making line alignment with blue laser alignment, users should be totally understanding required line length, line width and laser degree so as to get ideal line projection on required surfaces. The selection of line laser alignment is always more complex than selection of other type of cross and dot projecting laser alignments. Once users totally understand this basic information, laser professionals will recommend the most suitable line projection alignment laser with accurate laser degree and output power in continuous line projection.
The time users are making line projection, according to exact pointing distance, users should choose suitable output power laser alignment until getting required line positioning with ideal brightness and beam visibility. For close distance line projection in room operating occasions, it is necessary to get the ideal output power of no more than 5mW. In darkness operating occasions, a 5mW blue laser alignment is enough to make accurate line projection precisely and accurately. Under high brightness operating occasions, users should try to choose higher output powered alignment laser up 50mW. At long operating distance, users are always able to choose higher power blue laser alignment so as to produce bright enough blue reference line clearly on targeted surfaces. Meanwhile, the equipped operating voltage should be not less than 3.6V in order to produce sufficient power supply in continuous line generation.
