The most frequently asked question by learners is "How far can a laser pointer go?". A blue laser of 1W can easily reach up to 450 miles , and is ideal for presentations. The beam can be aimed at many different directions, and even towards vehicles moving. However, a powerful laser may extend its beam to the point that it is unable to be observed from the vehicle. In such situations the use of a laser with a higher power can be used.

The laser power of a pointer varies. A laser with a power of 200mW can be seen from over an entire mile. A 1000mW red laser can be visible for ten miles away. Certain lasers have a shorter range. According to ScienceDaily.com the world's largest laser spans 270 km. It is important to note that a projectile or a laser in space will emit light until it strikes something. The green laser however will only illuminate a small area across a space.

If you're worried about security, you may want to choose the green laser pointer. It's as bright as an 100-watt light bulb when viewed from three feet away, however, it's brighter than the quarter moon when you look upwards from 40, 000 feet. The green yellow laser pointer pointer on the other hand is not appropriate for use. It is recommended to purchase a reputable brand. If you're unsure, read reviews and ask your friends and family if they've had any accidents using these devices.

Although laser pointers can go for long distances but their range is restricted. This is because they can be too powerful in relation to the distance they reach. You'll want to keep them in a sealed enclosure to avoid spills that could happen. And while you're there, make sure to verify the capabilities that the laser can reach. It's a great way to be safe and avoid a dangerous situation!

There are a variety of methods to calculate the distance a laser can travel. The distance to the moon is 238 miles and it's possible to locate one that has a power of 5000mW. It's possible to use an flint laser of 50mW and be able to work as far as it's supposed to. Using a 5mW laser pointer could be risky and distracting.

Laser pointers are intended to function at a low power level. If you own one that's just a few thousand milliwatts in power and you are able to see it for as long as 1 mile. If you're on an airplane, it could be impossible to observe the laser's pointer unless pointed at your eyes. If you're in the far reaches of the wilderness the beam of light from the laser pointer could be seen from miles away.
