How far does a green laser go
WebAnswer: I'm sure you know not to actually point a laser at the sky because of the aviation safety hazards. But this is not what the question is asking. To answer 'how much is the power of the laser attenuated as it travels through the atmosphere?' we can look at the reverse problem: 'how much i... Web2 aug. 2024 · Relatively low visibility: A green laser level is four times brighter than a red laser level. The red beam compared to green at ambient lighting is less visible. Not suitable for exterior work: A red beam dissipates easily in daylight. Red diodes are susceptible to extreme temperature damage.

Web24 jun. 2011 · The lasers come in three colors: green (532 nm), blue (450 nm), and violet (405 nm). In terms of visual interference with pilots and motorists, the lasers have the following effects: A 2000 mW green laser is a flashblindness hazard to 5,200 feet (~1 mile), a glare/disruption hazard to 24,000 feet (4.5 miles), and a distraction hazard to 234,000 … Web4 jun. 2024 · In extremely clean air, a 532nm laser can potentially travel several kilometers. However, in more realistic scenarios, with moderate concentrations of particulates in the air, a 532nm laser is still likely to be able to travel several hundred meters, which is still a significant distance. Even in very polluted air, a 532nm laser can likely ...
Web9 apr. 2005 · It isn't working for the Chinese to English that well either. With a <5 mW green laser, you won't see the beam is direct sunlight, but you should be able to see the dot on whatever target you are aiming at. If you get a laser powerful enough to see the beam in bright sunlight, the laser will probably be strong enough for you to cut the tree ... Web13 sep. 2016 · You will have a much easier time seeing a green laser in broad daylight than red. Green is close to the center of the visible light spectrum at about 532 Nanometers. Red is higher on the spectrum at 635 Nanometers. Because of this, a red light will be obscured by other light, whereas a green will not.
WebHow far can a 5mw laser go? A 5 milliwatt laser: a distraction 2 miles away In the United States, lasers sold for pointing uses cannot exceed 5 mW.
