How Far Can a Laser Pointer Travel?
The most frequently asked question by pupils is "How far can a laser pointer go?". A 1W blue laser could easily reach up to 450 miles , and is useful for presentations. The beam is able to be directed in a variety of directions, including at moving vehicles. But a high power green laser-power laser could extend its beam to the point that it would be unable to be seen from vehicles. In these instances it is possible for a more powerful laser to be used.
The power of lasers in the pointer can vary. A green laser of 200mW could be seen over one mile. A red laser of 1000mW can be visible for ten miles away. Certain lasers have a shorter range. According to ScienceDaily.com, the world's longest laser measures 270 kilometers. It's worth noting that a projectile or laser within space will continue to emit light until it hits something. A green laser however will only show a small area across a room.
If you're concerned regarding safety, you may consider the laser pointer that is green. It's as bright as an 100-watt light bulb when viewed from three feet away however it's nearly as bright as a quarter moon when looking up from 40, 000 feet. A green laser pointer, on the other hand is not appropriate for use. You should always buy a reputable brand. If you're not sure, read reviews and ask friends and family whether they've experienced any issues using these devices.
Although laser pointers can go for a long distance however, their range is very restricted. This is due to the fact that they may be too powerful for the distance they reach. You'll need to keep the laser in a closed housing to avoid spills that could happen. And while you're there, make sure to verify the capabilities of the laser. This is a great way to protect yourself and avoid a dangerous situation!
There are numerous methods of determining the distance that a laser pointer can travel. The distance to the moon is 238 miles, and it's possible to locate one that's powered by 5500mW. It's possible to use a 50mW laser and it'll perform at least as well as it's intended to. Using a 5mW laser pointer could be risky and distracting.
Laser pointers are supposed to operate at a low power level. If you own a laser that is at a few thousand milliwatts that you can see for up to a mile. In the case of aircraft, you might be impossible to observe the laser's pointer unless pointed at your eyes. However, if you're in remotest part of the world the light of the laser pointer could be seen from miles away.
