What makes a good job to get clear and precise cross line generation for teaching and science experiments? Not relying on any prior cross line drawing or printing work, it is substituted by Berlinlasers 532nm green cross laser alignment. Employed by advanced 532nm green DPSS laser tech and a qualified glass coated lens, it not only projects highly bright green light at long extending distance, but also generates ultra fine, straight and bright two perpendicular green lines at long extending distance easily.

After correct use of output power and operating voltage DC power supply, green alignment laser allows freely adjusted cross line thickness and emitting direction, thus achieving easy reaching, quick response and noncontact green cross line source in distance. It is applied for visually demonstrates orthogonal coordinate systems, optical axes, symmetry, and imaging principles; the results are clear and easy to observe.
