![]() ![]() Beyond a certain distance the light attenuates into invisibility. You can test this yourself by buying a 1mw laser pointer from Staples or other stationary store and having a friend shine it into your own car parked at the other end of a football field or wherever to see the affect. ![]() This power of laser is too weak to make a noticeable distraction beyond about 500 feet, so it would be unlikely to affect a plane. The lasers in Christmas projectors are 1 milliwatt lasers. These types of lights are unlikely to affect an aircraft. To draw a pattern a laser light must move, so the time of illumination of a point is reduced when the device is working correctly.There are actually 2 laser leds, a red and a green, is it 2x1 mW or 2x0.5 mW? In practical the lasers probably can't illuminate the same eye, due to the divergence of their beams.As the class is not mentioned on the label, I would be careful when seeing this item.A class 2 laser led couldn't blind someone unless the person is at a few meters (15 m for temporary blindness and 3 m for eye damages, if the eye is forced to stay open).Most countries have regulations for dazzling a pilot, regardless of the mean and power used, it's the effect that is taken into account.The effects of a more diverged beam are weaker. The above distances are for a tightly focused beam, which is probably not the case of an inexpensive laser device. It can cause distraction, being brighter than surrounding lights, within 2 miles (3.2 km) of the laser. ![]()
