A common question from pupils is “How far can a laser’s pointer travel?”. A 1W blue laser could easily cover up to 450 miles and is ideal for presentations. The beam can be directed in many directions, including towards vehicles moving. However, a laser with a high power can radiate its beam so wide that it would be unable to be seen from a vehicle. In these situations, a higher-powered laser can be used.
The power of lasers in a pointer varies. A laser with a power of 200mW can be observed from a mile away. A 1000mW red laser could be seen from 10 miles away. Certain lasers have a shorter range. According to ScienceDaily.com, the world’s longest laser measures 270 kilometers. It is important to note that a projectile or “laser” in space will produce light as long as it strikes something. A green laser however will only display a tiny area across a space.
If you’re concerned about security, you may consider a laser pointer that is green. It looks as bright as an 100-watt light bulb when viewed from three feet away, however, it’s brighter than the quarter moon when you look up from the distance of 40,000 feet. Laser pointers that are green, however isn’t safe to use. Always choose an authentic brand. If you’re not sure, read reviews and ask friends and family if they’ve had any accidents using these devices.
While lasers can travel for a long distance but their range is only limited. This is due to the fact that they may be too powerful for the distance they can be able to cover. You’ll want to keep the laser in a closed housing to prevent accidental spills. While you’re there, make sure to verify the capabilities of the laser. It’s a great method to protect yourself and avoid danger!
There are many different ways to determine the distance that a laser pointer can travel. It is estimated that the distance from Earth to Moon will be 238 miles and it’s possible to find one that has a power of 500mW. You can use an flint laser of 50mW and work at least as far as it’s designed to. Utilizing a laser with a power of 5mW can be dangerous and can be distracting.
Laser pointers are intended to operate at a low power level. If you own a laser that is at a few thousand milliwatts that you can see for as long as 1 mile. In the case of the air, it could be impossible to see the laser’s pointer unless directed at your eyes. If you’re in the far reaches of the wilderness the beam of light from a laser pointer can be observed from miles away.
