If it is taking quite long time to make clear cross line measurement, thus laser tech engineer has begun to make continuous technical innovation of 515nm green laser diode tech, and being made into a quite practically used device of 515nm forest green cross laser alignment. In various precise device manufacturing work fields, on basis of the use of qualified glass coated lens with different fan angles and metal heat sink cooling system inside highly durable metal housing tube, this cross line laser module is projecting the most complex two perpendicular lines with accurate 90 degrees. After its proper installation and adjustment to correct position, it makes sure of highly clear and fine cross line alignment at various work distances.

The whole process of cross line measuring work is always continuing for quite long time. This 515nm forest green cross laser alignment gets basic use of import 515nm green laser diode. When it gets even higher thermal consumption than other visible laser devices, it should be equipping with correct operating voltage electric power source. The selection of 5V, 9V 1000mA DC power supply has just assured continuous forest green laser beam emission at several miles far away, but also generated highly clear green vertical and horizontal lines as long as 25 meters. 
Comparing with formal line or cross line measuring tool, 515nm forest green cross laser alignment is projecting the most complex two perpendicular green lines with accurate 90 degrees. The advanced use of glass coated lens allows freely selected fan angles of 10, 15 and 110 degree, thus projecting different dimension green cross line lengths within 0.5 meter to 6 meters. At the same time, owing to its freely adjusted laser beam focus, this green cross line laser module allows quick forest green laser light concentration, and highly fine green cross line projection at various work distances effectively.
With the assistance of a laser alignment mounting bracket and extending electric wires, within the maximum installed distance of 3 meters, 515nm green cross laser alignment enables the most convenient installation, and easy cross line projection onto any vertical or horizontal surface. Noncontact green cross line laser source is making clear indication for military targeting, laser medical therapy device, laser alignment for screen printing system and embroidery etc. Once high power green alignment laser is operating at quite long work distance, it is a necessity to wear correct laser safety glasses and avoid eye exposure until achieving safe and free use perfectly.
