A 1W blue laser could easily cover as far as 450 miles and can be useful in presentations. The beam can be aimed in a variety of directions, including at moving vehicles. But a high-power laser could extend its beam to the point that it would be unable to be seen from a vehicle. In such situations, a higher-powered laser can be employed.<br><br>The power of lasers in an object varies. A laser with a power of 200mW can be seen over a mile away. A red laser of 1000mW can be visible from ten miles away. Certain lasers have a shorter range. According to ScienceDaily.com, the world's longest laser is 270 kilometers long. It's important to know that a projectile or "laser" in space will produce light as long as it strikes something. A green laser, however, will only show a small space across the space.<br><br>If you're concerned about safety, you might prefer the laser pointer that is green. It's as bright an 100-watt light bulb when viewed from three feet away however it's nearly as bright as the quarter moon when you look upwards from 40, 000 feet. A green laser pointer, on the other hand isn't safe to use. Always choose a reputable brand. If you're unsure, read reviews and ask your friends and family whether they've experienced any issues using these devices.<br><br>While lasers can travel far distances but their range is restricted. This is due to the fact that they may be too powerful in relation to the distance they be able to cover. It is recommended to store them in a sealed enclosure to stop accidental spills. And while you're there, be sure to look over the distance that the laser can reach. It's a great way to be safe and avoid a dangerous situation!<br><br>There are numerous ways to determine the distance a laser can travel. The distance to the moon is 238 miles and it's possible to locate one with a power of 500mW. You can use the 50mW [http://www.bqinternet.com/index.php?a%5B%5D=%3Ca+href%3Dhttps%3A%2F%2Fwww.laserpointerstore.com%2Fstanford-uses-ordinary-cameras-and-laser-pointers-to-achieve-through-the-wall-perspective-even-your-id-can-be-seen-clearly%2F%3Elaser+power+meter%3C%2Fa%3E%3Cmeta+http-equiv%3Drefresh+content%3D0%3Burl%3Dhttps%3A%2F%2Fwww.laserpointerstore.com%2Fproducts%2Ffast-shipping-adjustable-focus-blue-laser%2F+%2F%3E laser ponter], and it will be able to work as far as it's intended to. Using a 5mW laser pointer could be risky and also distracting.<br><br>Laser pointers are supposed to function at a low power level. If you have an optical source that has a few thousand milliwatts, you can see it for as long as a mile. If you're on the air, it could be difficult to spot the laser's pointer unless directed at your eyes. But if you're in the remotest part of the world the beam of light from the laser pointer could be seen from miles away.
