A common question from students is “How far is a laser-pointer’s range?”. A 1W blue laser can easily travel up to 450 miles and is ideal for presentations. The beam can be directed at many different directions, and even at moving vehicles. But a high-power laser could radiate its beam so wide that it would be unable to be observed from the vehicle. In such situations it is possible for a more powerful laser to be employed.
The laser power of an object varies. A laser with a power of 200mW can be seen over one mile. A 1000mW red laser could be visible from ten miles away. Certain lasers have a smaller range. According to ScienceDaily.com the world’s largest laser spans 270 km. It is important to note that a projectile, also known as a laser in space will radiate light till it strikes something. A green laser however will only show a small area across a space.
If you’re worried regarding safety, you may prefer an green laser pointer. It’s as bright an 100-watt light bulb when viewed at three feet, however it’s nearly as bright as a quarter moon when looking upwards from the distance of 40,000 feet. A green laser pointer, in contrast, is not appropriate for green laser pointer use. It is recommended to purchase an authentic brand. If you’re not sure then read the reviews and ask your friends and family if they’ve had any accidents with these gadgets.
While laser pointers are able to travel far distances but their range is restricted. This is because they can be too powerful in relation to the distance they be able to cover. You’ll need to keep the laser in a closed housing to prevent accidental spills. Also, while you’re there don’t forget to check the capabilities for the range of laser. This is 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. The distance to the moon is 238 miles, and you can find one that has a power of 5000mW. It’s possible to use the 50mW laser, and it will be able to work as far as it’s intended to. A laser pointer with 5mW can be dangerous and distracting.
Laser pointers are intended to function at a low power level. If you’ve got one that’s just a few thousand milliwatts in power that you can see for as long as 1 mile. If you’re on an airplane, it might be impossible to observe the laser’s pointer unless pointed at your eyes. However, if you’re in middle of nowhere the light of a laser pointer can be seen from miles away.
