How Far Can A Laser Pointer Travel?
One of the most frequent questions from pupils is "How far can a laser's pointer travel?". A 1W blue laser can easily travel up to 450 miles and can be useful in presentations. The beam is able to be directed in a variety of directions, including towards vehicles moving. However, a powerful laser may spread its beam so far that it is unable to be seen from the vehicle. In such situations the use of a laser with a higher power can be used.
The power of lasers in the pointer can vary. A laser with a power of 200mW can be seen from over an entire mile. A 1000mW red laser could be seen from 10 miles away. Certain lasers have a smaller distance. According to ScienceDaily.com the world's longest laser spans 270 km. It's worth noting that a projectile or laser pointer battery within space will continue to radiate light till it hits something. The green laser, however, will only show a small area across a space.
If you're worried about safety, you might want to choose a laser pointer that is green. It's as bright an 100-watt light bulb when viewed from three feet away however it's nearly as bright as the quarter moon when you look up from 40,000 feet. The green laser pointer on the other hand, is not suitable for use. Always choose an authentic brand. If you're not certain then read the reviews and ask family and friends whether they've experienced any issues with these gadgets.
Although laser pointers can go far distances but their range is only limited. This is because they can be too powerful for the distance they can reach. It is recommended to store them in a sealed enclosure to prevent accidental spills. And while you're there, be sure to look over the capabilities that the laser can reach. It's a great way to ensure safety and avoid an unsafe situation!
There are many different methods of determining the distance that a laser pointer can travel. It is estimated that the distance from Earth to Moon will be 238 miles, and you can find one that has a power of 5500mW. It's possible to use an flint laser of 50mW and be able to work as far as it's designed to. A laser pointer with 5mW could be risky and distracting.
Laser pointers are supposed to function at a low power level. If you have an optical source that has at a few thousand milliwatts that you can see for up to one mile. If you're on aircraft, you may be impossible to observe the laser pointer unless it's directed at your eyes. But if you're in the middle of nowhere the beam of light from the laser pointer could be seen from miles away.
