How Far Can Laser Beam Could Run

It is a common question that how far can you see a laser beam. But without any answers. This may seems like a simple question just like how far can you see a star or something like this. In fact, laser is different field and few people are familiar with it. Here we'll look for a correct answer for you with the help of the professor of laser, which comes from Highlasers.com 

There are three points to be concerned.

1. Visible range of laser

What factors could decided the range and visible distance of laser pointer? The first is the wavelength. Wavelength by which decided the color of laser. And green laser beam is the most visible one. For the same optical power, the green laser beam will seem brighter than other colors because the human eye is most sensitive at low light levels in the green region of the spectrum. The redder and bluer wavelength decreases sensitivity. Next one is output power. The higher the power is, the brighter the beam is. They two are the determining factors of the brightness the laser beam could be. So the green laser pointer with 3000mW would be unbeatable.

2. Adjust the Focus of Laser

Another distinctly important factor is the focus of laser pointer. Most of laser models have adjusting design features. For lasers that offer switch to choose to thin or widen the beam. you can pinpoint targets at close or long distances making it even better for long range targeting.

3. How to Measure the Length

Above two points is according the laser itself. If everything all be done, and how can we measure the length we could see. 200mW green lasers will be visible for more than 10 miles, and blue lasers with 1,000mW or more will be visible for 10 miles. There are other factors like cloud coverage and fog. But as a basic rule of human eyes, you can expect over 100 miles of visible distance on green more than 200mW lasers and more than 1,000mW blue lasers.

The last I should mention here is the safety. It is dangerous to look the beam directly with a naked eyes. Wear a pair of laser safety goggles from Highlasers will protect your eyes a lot. For the best place to buy high power laser pointer online, look no further than www.highlasers.com
