The most frequently asked question by students is "How far can a laser's pointer travel?". A 1W blue laser could easily travel up to 450 miles , and is useful for presentations. The beam is able to be directed in many directions, including towards vehicles moving. However, a powerful laser may radiate its beam so wide that it would be unable to be seen from the vehicle. In such situations it is possible for a more powerful laser light pen to be employed.

The laser power of a pointer varies. A green laser of 200mW could be seen over an entire mile. A 1000mW red laser can be visible from ten miles away. Certain lasers have a smaller distance. According to ScienceDaily.com the world's largest laser measures 270 kilometers. It is important to note that a projectile, also known as a 'laser' in space will radiate light till it strikes something. The green laser however will only show a small area of a space.

If you're worried regarding safety, you may prefer an laser pointer that is green. It's as bright a 100-watt light bulb from three feet away, laser light pen however it's nearly as bright as a quarter moon when looking up from 40, 000 feet. Laser pointers that are green, on the other hand is not safe to use. It is recommended to purchase a reputable brand. If you're not sure you should read reviews, and ask family and friends about any incidents they've experienced with these gadgets.

While laser pointers are able to travel for long distances, their range is only limited. This is due to the fact that they may be too powerful for the distance they reach. You'll need to keep them in a sealed enclosure to stop accidental spills. While you're there, don't forget to check the distance for the range of laser. It's a great way to protect yourself and avoid a dangerous situation!

There are many different methods to calculate the distance a laser can travel. The distance to the moon is 238 miles and it's possible to find one with a power of 5500mW. It's possible to use an flint laser of 50mW and be able to work as far as it's intended to. Utilizing a laser with a power of 5mW could be risky and distracting.

Laser pointers are supposed to function at a low power level. If you've got an optical source that has a few thousand milliwatts and you are able to see it for up to one mile. If you're in aircraft, you could be difficult to spot the laser pointer unless it's focused on your eyes. If you're in the remotest part of the world, the light from a laser pointer can be observed far away.
