In any occasion where users are trying to make extremely clear cross line generation at quite long work distance, not the same as any simple cross line printing device, it would be the best experience for user to use advanced laser tech applied Berlinlasers blue cross laser alignment. It is generating highly intense and bright blue laser beam from 445nm blue laser diode directly, beginning with high power within 50mW to 100mW, blue cross line laser source will be clearly visible and accurate within the maximum work distance of 25 meters.
When blue cross laser alignment is adopting qualified glass coated lens with selected lens degree of 10, 15 and 110 degree, it will generate different cross line length within 0.5 meter to 6 meters. This focus beam emitted cross line laser device is just used as an accessory part. It is not only workable for formal industrial cross line measuring work, but also getting the most satisfied blue cross line generation for laser show, laser displaying, military targeting and high tech cross line alignment works perfectly.
