One of the most frequent questions from students is "How far can a laser pointer go?". A 1W blue laser can easily travel as far as 450 miles and is useful for presentations. The beam can be directed in a variety of directions, including at moving vehicles. But a high-power laser could spread its beam so far that it is unable to be seen from vehicles. In these instances it is possible for a more powerful laser to be used.

The power of lasers in a pointer varies. A 200mW green laser can 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 spans 270 km. It is important to note that a projectile or 'laser' within space will continue to produce light as long as it hits something. A green laser, however, will only show a small area of a space.

If you're worried about security, you may prefer an green laser pointer. It's as bright 100-watt light bulbs at three feet, however it's nearly as bright as a quarter moon when looking upwards from 40, 000 feet. A green laser pointer, in contrast, is not safe to use. It is recommended to purchase an authentic brand. If you're not certain you should read reviews, and ask your friends and family whether they've experienced any issues using these devices.

Although laser pointers can go far distances however, their range is very limited. They can be too powerful for the distance they can reach. You'll need to keep them in a sealed housing to avoid spills that could happen. And while you're there, make sure to verify the range that the laser can reach. It's a great way to be safe and avoid danger!

There are a variety of ways to determine the distance a laser pointer can travel. The distance to the moon is 238 miles, and you can find one that's powered by 5500mW. It's possible to use the 50mW laser, and it will work at least as far as it's supposed to. Utilizing a laser pointer battery size with a power of 5mW could be risky and distracting.

Laser pointers are designed to operate at a low power level. If you've got one that's a few thousand milliwatts that you can see for as long as one mile. If you're on an airplane, it may be impossible to see the laser pointer , unless it's focused on your eyes. However, if you're in far reaches of the wilderness the light of the laser pointer can be observed from miles away.
