A common question from students is "How far is a laser-pointer's range?". A 1W blue laser can easily travel as far as 450 miles and is ideal for presentations. The beam can be directed in many directions, including towards vehicles moving. However, a powerful laser may radiate its beam so wide 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 lasers in an object varies. A green laser of 200mW could be seen from over an entire mile. A 1000mW red laser could be visible for ten miles away. Some lasers have a shorter distance. According to ScienceDaily.com the world's largest laser is 270 kilometers long. It's worth noting that a projectile or "laser" in space will produce light as long as it strikes something. The green laser however will only illuminate a small area across a space.

If you're concerned regarding safety, green laser pointer you may consider an laser pointer that is green. It's as bright a 100-watt light bulb at three feet, however it's nearly as bright as a quarter moon when looking upwards from 40, 000 feet. The green laser pointer however isn't suitable for use. It is recommended to purchase an authentic brand. If you're not sure, read reviews and ask friends and family whether they've experienced any issues using these devices.

While lasers can travel for a long distance, their range is only limited. This is because they can be too powerful for the distance they reach. You'll want to keep them in a sealed enclosure to stop accidental spills. And while you're there, make sure to verify the capabilities of the laser. It's a great method to ensure safety and avoid danger!

There are numerous methods to calculate the distance a laser pointer can travel. Distance to moon 238 miles and you can find one that's powered by 500mW. It's possible to utilize the 50mW laser, and it will perform at least as well as it's designed to. A laser pointer with 5mW can be dangerous and also distracting.

Laser pointers are intended to function at a low power level. If you've got one that's a few thousand milliwatts, you can see it for as long as a mile. In the case of the air, it could be impossible to observe the laser pointer unless it's pointed at your eyes. However, if you're in remotest part of the world the light of a laser pointer can be seen far away.
