In order to get clear and fine enough line indication at various work distance, including sunlight, it would be the best choice to operate a 532nm green line laser module. It emits the most visible green laser light from a middle wavelength 532nm green DPSS laser. Being made with metal heat sink and APC, ACC driving circuit board inside its durable metal housing tube, it enables easy carrying, long lasting and high stability green line alignment in use. 
Being made with a qualified glass coated lens within 10 to 110 degree fan angles, after passing through up to 24 hours beam stability test, this laser line generator emits high linear quality green line within 0.5 meter to 6 meters line lengths. Cooperating with adjustable focus optic lens design, it enables freely adjusted laser line fineness, thus focused into an increasing brightness and fineness green line source at greater distance and high lighting working occasions conveniently.
Applications: laser cutting, saw mill, lumber machine, textile garment processing, laser medical therapy and high tech
