When 50mW pro red cross laser alignment is trying to make continuous cross line projection onto various working surfaces, it just gets constant power source from an external AC/DC adapter. In occasion that it is operating in various working environments, after the acceptation of wide range electric current of 100V to 240V and correct selection of 9V 1000mA DC power supply, this 50mW 635nm red laser module is easily getting continuous red laser beam and red cross line source emission at quite long work distance.
Being made with the most qualified glass coated lens, not the same as formally used plastic coated lens, 50mW pro red cross laser alignment is performing with high intensity and high transmittance red laser light emission. When it is pointing under any other harsh working occasion, such as moisture or dust, owing to special use of glass window in front of beam aperture, it just gets highly stable performance and highly clear red cross line projection in long time use. In occasion that it makes constant cross line projection within 8 to 10 hours per day, it is achieving superior nice laser light cycling use and up to 85% laser beam stability in continuous use.
Owing to the use of APC, ACC driving circuit board, even though there is increasing temperature of laser tube, this 50mW pro red cross laser alignment still keeps work with constant output power and electric current supply. The genuine cross line projection gets no worrying about laser light decay or blur. At the same time, when users are making proper adjustment of laser beam focus and cross line projecting direction within three dimensions, this red alignment laser gets high speed red laser light focusing and highly fine red cross line projection at long work distance. Any time users are realizing any potential thermal energy hurt to eyes and wearing correct 635nm wavelength preventing laser safety goggles, it just makes high security and high accuracy cross line alignment in distance perfectly.
