Not the same as any prior cross line drawing or printing work, either it is pointing at quite long distance or formal lighting, it always makes a good job to operate a highly intense beam emitting tool of a 445nm blue crosshair laser module. It keeps work with direct blue laser light emission from a 445nm blue laser diode. Not as bright as a 473nm blue DPSS laser system, equipped with thermal emitting system, it just enables long lasting blue laser light emission and high stability blue cross line alignment in long lasting use. 
Being made with a qualified glass coated lens and strict laser beam stability test up to 24 hours, the genuine use of a cross line laser module is achieving high precision and high fineness blue cross line projection within long extending distance of 25 meters. It gets different fan angles of 10, 15 and 110 degree, which projects different cross line lengths of 0.5 meter to 6 meters. Under operation with proper installation and correct use of both of output power and optic lens fan angle, after its freely adjusted cross line fineness, it provides users excellent cross line alignment solutions for all precise machinery processing work fields perfectly.
Applications: industrial precise machinery processing, laser medical therapy, military targeting, laser medical therapy, scientific experiment and high-tech
