When 50mW green cross laser alignment is making continuous cross line projection at great distance, any type of manual cross line drawing work is not helpful at all. It selects an external DC input power supply as its electric power source, after getting quite larger space inside laser module tube for metal heat sink cooling system, it is not only keeping work with highly intense green laser beam emission, but also obtaining superior nice thermal emitting in continuous use. The special use of AC/DC adapter has just made green cross line laser applying for various working environments. After correct converting into 9V 1000mA DC power source, it just keeps work with high brightness green cross line projection at great distance and high lighting occasions.
No matter what kind of working surface it is pointing, 50mW green cross laser alignment is requiring to be used in multiple working environments and generate different dimension cross line source in distance. The special use of qualified glass coated lens is workable with selected fan angle of 10, 15 or 110 degree. It projects different dimension cross line length within 0.5 meter to 6 meters, while always keeping high linear quality and high fineness, no worrying about laser light decay or dim in continuous use.
Whenever 50mW 532nm green cross laser alignment is passing through quite strict laser beam stability tests up to 24 hours and quite special use of glass window in front of laser beam aperture, it is just workable with super clear green cross line projection and stable performance, including any moisture or dust etc. After quite easy adjustment of laser beam focus in front of laser beam aperture, once powerful green laser radiation is focusing, this alignment laser is achieving highly fine green cross line in use. Unless it is pointing under sunlight, after correct wearing of laser safety goggles and avoiding eye exposure to laser beam aperture, it achieves safe and no mistake measurement constantly.
