The most frequently asked question by students is “How far can a laser pointer go?”. A blue laser of 1W can easily cover up to 450 miles and is useful for presentations. The beam can be aimed at many different directions, and even towards vehicles moving. However, a laser with a high power can extend its beam to the point that it is unable to be seen from vehicles. In these situations the use of a laser with a higher power can be used.
The power of lasers pointers in an object varies. A laser with a power of 200mW can be seen from over an entire mile. A 1000mW red laser can 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’s important to know that a projectile, also known as a laser in space will continue to radiate light till it strikes something. A green laser however will only show a small area across a room.
If you’re worried regarding safety, you may want to choose the green laser pointer. It’s as bright a 100-watt light bulb from three feet away but it’s as bright as a quarter moon when looking up from 40, 000 feet. The green laser pointer however is not suitable for lasers pointers use. Always choose a reputable brand. If you’re not certain, read reviews and ask family and friends whether they’ve experienced any issues using these devices.
While laser pointers are able to travel far distances, their range is limited. This is because they can be too powerful in relation to the distance they cover. It is recommended to store the laser in a closed housing to avoid spills that could happen. Also, while you’re there make sure to verify the capabilities of the laser. This is a great way to ensure safety 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 has a power of 500mW. It’s possible to utilize an flint laser of 50mW and 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 designed to function at a low power level. If you have an optical source that has a few thousand milliwatts and you are able to see it for as long as 1 mile. If you’re on aircraft, you might be impossible to see the laser’s pointer unless directed at your eyes. If you’re in the middle of nowhere, the light from the laser pointer can be seen far away.
