A common question from learners is "How far can a laser pointer go?". A blue laser of 1W can easily reach up to 450 miles and is useful for presentations. The beam can be aimed in a variety of directions, including at moving vehicles. However, a powerful laser may extend its beam to the point that it would be unable to be seen from a vehicle. In such situations the use of a laser with a higher power can be employed.

The power of the laser beam from the pointer can vary. A laser with a power of 200mW can be seen over an entire mile. A red laser pointer battery size of 1000mW can be seen from 10 miles away. Certain lasers have a smaller range. According to ScienceDaily.com the world's longest laser is 270 kilometers long. It's important to know that a projectile or a 'laser' within space will continue to emit light until it strikes something. A green laser, however, will only show a small space across the room.

If you're worried about safety, you might prefer a green laser pointer. It looks as bright as a 100-watt light bulb from three feet away, however, it's brighter than the quarter moon when you look upwards from 40, 000 feet. The green laser pointer in contrast isn't safe to use. Always choose a reputable brand. If you're not sure, read reviews and ask your friends and family about any incidents they've experienced with these gadgets.

Although laser pointers can go far distances however, their range is very restricted. They can be too powerful for the distance they reach. You'll want to keep them in a sealed housing to prevent accidental spills. While you're there, laser pointer battery size be sure to look over the range for the range of laser. This is a great way to be safe and avoid an unsafe situation!

There are a variety of ways to determine the distance a laser can travel. The distance to the moon is 238 miles, and it's possible to find one that has a power of 5500mW. It's possible to use an flint laser of 50mW and perform at least as well as it's intended to. Using a 5mW laser pointer can be dangerous and also distracting.

Laser pointers are designed to operate at a low power level. If you own one that's a few thousand milliwatts that you can see for up to 1 mile. In the case of the air, it may be impossible to observe the laser's pointer unless directed at your eyes. But if you're in the middle of nowhere, the light from the laser pointer can be observed far away.
