The generated forest green laser light from a 515nm green laser diode module is near the peak of the human eye’s visible light sensitivity. At the same power, its brightness is much higher than red light (such as 650nm), making it clearly visible even in strong sunlight or at long distances. When it gets low laser beam divergence and special use of adjustable focus optic lens, after its immediate forest green laser light projection from beam aperture, this 515nm green dot laser alignment makes efficient conversion of increasing accuracy and brightness green reference dot projection at a longer distance. Owing to its good focused green laser light emission, within a minimum spot diameter down to micrometers, it is meeting the alignment requirements of precise scenes. Compared with any other visible red lasers, once it is pointing under outside or other high lighting working environments etc, it gets enhanced interference immunity in outdoor and high-brightness environments, eliminating the need for dark backgrounds for identification.

This 445nm blue crosshair laser module maintains exceptional visibility in both natural and bright sunlight in textile workshops, far superior to red lasers. Operators can clearly identify positioning lines without shielding. When it gets constant electric power source supply, even though textile fabrics (such as chemical fibers and silk) are highly reflective, however, blue laser light still gets even higher penetration and contrast, which can effectively prevent blurring caused by reflections, ensuring accurate blue cross line positioning. Within the lowest energy and power consumption, this blue cross laser alignment always generates less heat at typical positioning powers, which can be used directly against flammable fabrics such as cotton, linen, and silk without the risk of burns.
