A common question from learners is “How far can a laser pointer go?”. A 1W blue laser can easily cover up to 450 miles and can be useful in presentations. The beam can be aimed in many directions, including towards moving vehicles. But a high-power laser could radiate its beam so wide that it would be unable to be seen from the vehicle. In these instances the use of a laser with a higher power can be used.

The power of lasers in a pointer varies. A green laser of 200mW could be observed from a mile away. A 1000mW red laser could be visible from ten miles away. Certain lasers have a shorter distance. According to ScienceDaily.com, the world’s longest laser is 270 kilometers long. It’s worth noting that a projectile or a “laser” in space will continue to radiate light till it strikes something. A green laser however will only illuminate a small space across the room.

If you’re worried about security, you may want to choose the green laser pointer. It’s as bright an 100-watt light bulb when viewed at three feet, but it’s as bright as a quarter moon when looking up from 40,000 feet. Laser pointers that are green, however is not suitable for use. Always choose an established brand. If you’re not sure, read reviews and ask friends and family whether they’ve experienced any issues with these gadgets.

While lasers can travel for long distances, their range is limited. This is because they can be too powerful in relation to the distance they reach. You’ll need to keep them in a sealed housing to avoid spills that could happen. Also, while you’re there don’t forget to check the capabilities of the laser. It’s a great method to be safe and avoid danger!

There are many different methods of determining the distance that a laser pointer can travel. Distance to moon 238 miles, and it’s possible to locate one that’s powered by 500mW. You can use an flint laser of 50mW and be able to work as far as it’s supposed to. Using a 5mW laser pointer can be dangerous and also distracting.

Laser pointers are designed to function at a low power level. If you have one that’s a few thousand milliwatts that you can see for up to a mile. If you’re in aircraft, you could be impossible to see the laser pointer unless it’s pointed at your eyes. If you’re in the middle of nowhere, the light from the laser pointer can be seen from miles away.
