How Far Can a Laser Pointer Travel?

A common question from students is “How far can a laser pointer go?”. A blue laser of 1W can easily reach up to 450 miles and is useful for presentations. The beam can be aimed in many directions, including towards moving vehicles. However, a laser with a high power can extend its beam to the point that it is unable to be observed from vehicles. In these instances the use of a laser with a higher power can be used.

The power of the laser beam from the pointer can vary. A laser with a power of 200mW can be seen over one mile. A red laser of 1000mW can be visible for ten miles away. Certain lasers have a smaller distance. According to ScienceDaily.com the world’s longest laser measures 270 kilometers. It’s important to know that a projectile or laser in space will continue to produce light as long as it strikes something. The green laser, however, will only show a small area of a room.

If you’re concerned about safety, you might want to choose 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 brighter than a quarter moon when looking upwards from 40, 000 feet. The green laser pointer on the other hand isn’t appropriate for use. Always choose an established brand. If you’re not sure you should read reviews, and ask friends and family about any incidents they’ve experienced with these gadgets.

While laser pointers are able to travel for long distances however, their range is very only limited. This is because they can be too powerful for the distance they be able to cover. It is recommended to store them in a sealed housing to avoid spills that could happen. Also, while you’re there be sure to look over the range for the range of laser. This is a great way to protect yourself and avoid a dangerous situation!

There are many different methods of determining the distance a laser can travel. Distance to moon 238 miles, and it’s possible to find one that has a power of 5000mW. It’s possible to utilize an flint laser of 50mW and perform at least as well as it’s designed to. Using a 5mW laser pointer could be risky and also distracting.

Laser pointers are designed to function at a low power level. If you own a laser that is a few thousand milliwatts that you can see for as long as a mile. If you’re on the air, it might be difficult to spot the laser’s pointer unless focused on your eyes. If you’re in the far reaches of the wilderness the light of a laser pointer can be seen far away.
