The most frequently asked question by learners is "How far can a laser pointer go?". A 1W blue laser can easily cover up to 450 miles and is ideal for presentations. The beam can be aimed in a variety of directions, including at moving vehicles. However, a laser with a high power can extend its beam to the point that it is unable to be seen from vehicles. In these instances, a higher-powered laser can be used.

The power of lasers in the pointer can vary. A laser with a power of 200mW can be observed from an entire mile. A red laser of 1000mW can be visible from ten miles away. Certain lasers have a smaller range. According to ScienceDaily.com the world's longest laser is 270 kilometers long. It's worth noting 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 concerned about security, you may want to choose an laser pointer that is green. It's as bright as 100-watt light bulbs from three feet away, however it's nearly as bright as the quarter moon when you look up from 40, 000 feet. Laser pointers that are green, gatling laser in contrast is not safe to use. You should always buy a reputable brand. If you're unsure then read the reviews and ask family and friends if they've had any accidents with these gadgets.

While laser pointers are able to travel far distances, 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. It is recommended to store the laser in a closed housing to avoid spills that could happen. While you're there, make sure to verify the capabilities that the laser can reach. 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. It is estimated that the distance from Earth to Moon will be 238 miles, and it's possible to find one that's powered by 500mW. You can use an flint laser of 50mW and work at least as far as it's designed to. Using a 5mW laser pointer can be dangerous and distracting.

Laser pointers are designed to operate at a lower power level. If you've got a gatling laser that is just a few thousand milliwatts in power that you can see for up to one mile. If you're in the air, it could be impossible to observe the laser pointer unless it's pointed at your eyes. If you're in the middle of nowhere the beam of light from a laser pointer can be observed far away.
