The most frequently asked question by learners is "How far is a laser-pointer's range?". A blue laser of 1W can easily cover as far as 450 miles and can be useful in 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's impossible to be observed from the vehicle. In these situations, a higher-powered laser can be used.

The laser power of the pointer can vary. A 200mw laser green laser can be seen from over an entire mile. A red laser of 1000mW can be visible for ten miles away. Certain lasers have a smaller range. According to ScienceDaily.com, the world's longest laser measures 270 kilometers. 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 show a small space across the room.

If you're concerned about safety, you might consider an laser pointer that is green. It looks as bright as an 100-watt light bulb when viewed from three feet away, but it's as bright as the quarter moon when you look upwards from the distance of 40,000 feet. A green laser pointer, however, is not appropriate for use. Always choose a reputable brand. If you're not certain, read reviews and ask family and friends whether they've experienced any issues with these gadgets.

While laser pointers are able to travel far distances but their range is restricted. They can be too powerful for the distance they reach. You'll need to keep the laser in a closed housing to avoid spills that could happen. And while you're there, don't forget to check the capabilities for the range of laser. It's a great way to be safe and avoid a dangerous situation!

There are many different ways to determine the distance that a laser pointer can travel. It is estimated that the distance from Earth to Moon will be 238 miles, and you can find one with a power of 5500mW. It's possible to use the 50mW laser, and it will perform at least as well as it's designed to. Utilizing a laser with a power of 5mW could be risky and also distracting.

Laser pointers are supposed to function at a low power level. If you own an optical source that has just a few thousand milliwatts in power and you are able to see it for as long as 1 mile. If you're in the air, it might be difficult to spot the laser pointer unless it's focused on your eyes. But if you're in the remotest part of the world the beam of light from the laser pointer can be seen far away.
