A common question from students is «How far can a laser’s pointer travel?». A blue laser of 1W can easily travel up to 450 miles and is useful for presentations. The beam can be aimed at many different directions, and even towards moving vehicles. But a high-power laser could spread its beam so far that it would be unable to be seen from the vehicle. In these situations, a higher-powered laser can be used.
The power of the laser beam from the pointer can vary. A green laser of 200mW could be observed from a mile away. A 1000mW red laser could be visible from ten miles away. Some lasers have a shorter range. According to ScienceDaily.com the world’s largest laser spans 270 km. It’s important to know that a projectile or a «laser» in space will radiate light till it strikes something. The green laser however will only illuminate a small space across the space.
If you’re worried about safety, you might consider a laser pointer that is green. It looks as bright as a 100-watt light bulb from three feet away, however, it’s brighter than a quarter moon when looking upwards from 40, 000 feet. The green laser pointer in contrast, is not appropriate for use. Always choose a reputable brand. If you’re unsure then read the reviews and ask friends and family whether they’ve experienced any issues using these devices.
Although laser pointers can go for long distances, their range is restricted. This is because they can be too powerful for the distance they can cover. You’ll want to keep them in a sealed enclosure to stop accidental spills. And while you’re there, make sure to verify the capabilities that the laser pointer near me can reach. This is a great way to protect yourself and avoid an unsafe situation!
There are many different methods of determining the distance a laser pointer can travel. Distance to moon 238 miles and it’s possible to locate 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. Using a 5mW laser pointer can be dangerous and distracting.
Laser pointers are supposed to operate at a lower power level. If you have one that’s a few thousand milliwatts that you can see for as long as 1 mile. If you’re on an airplane, it could be difficult to spot the laser pointer unless it’s directed at your eyes. However, if you’re in middle of nowhere, the light from the laser pointer could be seen from miles away.
