The most frequently asked question by learners is "How far is a laser-pointer's range?". A 1W blue laser can easily reach as far as 450 miles and can be useful in presentations. The beam can be aimed in many directions, including at moving vehicles. But a high-power laser could spread its beam so far that it would be unable to be observed from vehicles. In such situations the use of a laser with a higher power can be used.

The laser power of an object varies. A green laser of 200mW could be seen from over a mile away. A 1000mW red laser could be seen from 10 miles away. Certain lasers have a smaller distance. According to ScienceDaily.com the world's largest laser spans 270 km. It's worth noting that a projectile or "laser" in space will continue to radiate light till it strikes something. The green laser, green laser pointer however, will only show a small area across a room.

If you're worried about safety, you might consider a laser pointer that is green. It looks as bright as a 100-watt light bulb at three feet, however, it's brighter than the quarter moon when you look upwards from 40, 000 feet. A green laser pointer, in contrast is not appropriate for use. Always choose an established brand. If you're unsure then read the reviews and ask your friends and family if they've had any accidents with these gadgets.

While laser pointers are able to travel for a long distance but their range is only limited. This is due to the fact that they may be too powerful for the distance they reach. It is recommended to store them in a sealed housing to avoid spills that could happen. Also, while you're there don't forget to check the capabilities that the laser can reach. It's a great method to ensure safety and avoid a dangerous situation!

There are a variety of ways to determine the distance that a laser pointer 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 utilize the 50mW laser, and it will be able to work as far as it's supposed to. Utilizing a laser with a power of 5mW can be dangerous and also distracting.

Laser pointers are intended to operate at a low power level. If you've got an optical source that has at a few thousand milliwatts, you can see it for as long as one mile. If you're on an airplane, it might be impossible to see the laser's pointer unless directed at your eyes. However, if you're in remotest part of the world the beam of light from the laser pointer could be observed far away.
