One of the most frequent questions from students is "How far can a laser pointer go?". A 1W blue laser can easily reach up to 450 miles , and is ideal for presentations. The beam can be aimed in a variety of directions, including at moving vehicles. But a high-power laser could radiate its beam so wide that it is unable to be seen from a vehicle. In such situations, a higher-powered laser can be used.

The power of lasers in an object varies. A laser with a power of 200mW can be observed from one mile. A red laser of 1000mW can be seen from 10 miles away. Certain lasers have a smaller range. According to ScienceDaily.com the world's longest laser spans 270 km. It's important to know that a projectile, also known as a "laser" in space will continue to radiate light till it hits something. A green laser however will only show a small area of a space.

If you're concerned about security, you may want to choose the laser ultra pointer that is green. It looks as bright as 100-watt light bulbs at three feet, but it's as bright as the quarter moon when you look upwards from 40, 000 feet. The green laser pointer in contrast is not suitable for use. Always choose a reputable brand. If you're not certain then read the reviews and ask your friends and family whether they've experienced any issues with these gadgets.

Although laser pointers can go far distances however, their range is very only limited. This is due to the fact that they may be too powerful for the distance they can be able to cover. You'll need to keep them in a sealed housing to avoid spills that could happen. Also, while you're there make sure to verify the capabilities of the laser. This is a great way to ensure safety and avoid an unsafe situation!

There are many different methods of determining the distance a laser can travel. Distance to moon 238 miles and you can find one that's powered by 5500mW. You can use the 50mW laser, and it will be able to work as far as it's designed to. Using a 5mW laser pointer could be risky and also distracting.

Laser pointers are intended to function at a low power level. If you have an optical source that has just a few thousand milliwatts in power, you can see it for as long as a mile. If you're on an airplane, it could be impossible to observe the laser's pointer unless directed at your eyes. But if you're in the middle of nowhere the light of the laser pointer can be observed far away.
