HOW CAN DC POWER 445NM BLUE LASER DIODE MODULE WORK AT LONG DISTANCE?

Different from a simple blue laser pointer only used for temporary dot positioning works, in order to make long time dot alignment, it should be a quite nice solution to operate a direct diode emission made Berlinlasers 445nm blue laser diode module. It enables constant blue laser beam and blue reference dot projection from the laser beam aperture. When ultra compact size tube made laser device gets proper installation, it brings users easy reaching and good direction dot alignment onto all working surfaces constantly.
The usual use of a laser diode module is working for a quite long time, thus it still has to work with stable and reliable dot indication in long lasting use. Being made with a qualified optic lens and glass window, it also gets strict laser beam stability test up to 24 hours. It is able to work with high quality blue laser light source emission and highly precise blue dot projection within long extending distance of 25 meters and formal lighting working occasions etc.
Applications: industrial precise dot alignment, laser show, laser displaying, decoration, laser communication and optical instrument etc.
