Taking the curvature of the Earth into account, you'd be hard pressed to shine it on anything 50 miles away except an aeroplane. I wonder if any of our maths genii can calculate the height it would shine at over a range of 50 miles. I feel a new thread coming on Example: crisp night with low humidity I can see the beam from my green laser as a nice thin line hitting low clouds and hitting a tower several miles away. However, on a foggy night the beam appears as a fat glowing light saber sort of thing and only travels a few hundred meters at best At the Nebraska Star Party, we could often see the beams from the simple 5 mw lasers being used for the Beginner's Field School star talk going up into the sky at distances of up to nearly 600 feet from where they were being fired Class 3 can go up to 100mw but are not classified for civilian use. For firearms, you need a laser to project a beam as far as you want to shoot. For most handguns, 100 feet is more than you will ever need. For rifles, you can make the call, but I rarely need to shoot anything more than one-quarter mile away

The photos were taken with the lasers about 10 feet from the target. That's closer than I shot the drills, but my camera can't see the laser as well as a human so the lasers had to be moved in for the pictures. In the low light photo, you can see some speckling in the green dot, which occurs when the laser's lens gets dirty For the average AK with a set back, side mount I would say optimum accurate range is 50 yards out to 100 yards on the far range. 50 yds is cantelope size accuracy, 100 yds 55 gallon drum size accuracy. Now that is my experience with a nice AK I built with an inexpensive green Chinese laser/mount with just run of the mill foreign ammo

I mean come on, a 532 nm green laser wavelength is obviously superior to a laughable 650 nm red laser wavelength. And unlike a red laser, the green beam itself can be seen in mid-air in dark conditions, not just the laser beam dot The green laser's beam, whether it's a pulsed green laser or a steady green laser beam when you hold down the button like most green laser pointers, being signifigantly brighter than a red laser's of the same power output (possibly as much as 55 times brighter), can be seen further away, and, when used at night, or in dark places, especially. What it looks like from the helicopter when laser is aimed at it. This is becoming a problem for commercial passenger planes also, usually on landing approa.. In total darkness we can see a <5mW 650nm laser around 500 - 1km away when it shines on a white surface. The divergence will make that projected dot 1km away a large dot that reach 20-30m in diameter, and very faint. Green YAG laser pointers at the same power, is in comperison visible up to 4-5km away. 7.2K view The green light is generated through a multi-step process, usually beginning with a high-power (typically 100-300 mW) infrared aluminium gallium arsenide (AlGaAs) laser diode operating at 808 nm

The FAA found that a 5-mW green laser pointer can cause retinal burns at distances up to 14 meters (50 feet) and flashblindness, afterimages, or glare problems up to 350 meters (nearly a quarter mile). Even at a range of 3 kilometers (2 miles), a green laser pointer can still interfere with a pilot's vision badly enough to prompt an aborted. No, not with envy. Let the onlookers do that when they see your green laser pointers. These lasers have 532nm green laser wavelength. They are generally used for pointing at star constellations. The green laser light works with the help of Diode Pumped Solid State Frequency Doubled (DPSSFD) laser technology A laser like that would need to put out about 500,000 watts of power—100 million times more powerful than your pocket laser pointer. These lasers typically operate in the infrared spectrum, which is invisible to humans. But for the sake of this exercise we'll assume that both Starman and the Martians can see in the infrared This class requires 5 to 499 milliwatts of power to use and is not quite as powerful as Class 4, but it can cause damage if the laser is applied for an extended duration. Class 3B lasers can heat the skin and materials if the beam remains on the object at a close range. The distance Class 3B laser beams can travel to is up to 116,890 feet or 99. The Z-Bolt Military Pride Green Laser Pointer has a wavelength of 532 nm and a maximum range of 5 miles. The green beam is perfect for beginner stargazers to accurately point to objects in the sky. We were happy to see that this brightest laser pointer has an IR filter for eye protection and additional safety

This color of laser can be produced in a small, handheld tool that looks like a miniature flashlight. Amateur astronomers often use a green laser because it reaches so far into the atmosphere, with a visible beam, that you can point out stars and galaxies

March 2006 5mW Green Laser Pointer for Astronomy I bought the BTG-6-plus laser pointer from Z-bolt.com (Beam of Light Technologies) to use as a sky pointer for showing my kids, my friends, and my friends' kids the sky. I've seen all sorts of claims from various different people about how well or poorly these work, so I thought I'd write up a review here It's not more powerful—both emit a full watt of power—but the green light's wavelength is vastly more visible. Wicked Laser claims an 85 mile range, which means it could penetrate the Earth's..

A 532 nm green laser wavelength is obviously superior to a laughable 650 nm red laser wavelength Twenty years ago, a green laser would set you back $100,000 and occupy a good-sized dining room table. Today, you can buy a green laser pointer the size of a ball point pen for $15

A 0.99 mW Class 2 laser beam can temporarily flashblind a pilot or driver, causing afterimages, within 240 ft (73 m) of the laser. It can cause glare, blocking a pilot or driver's vision, within 1050 ft (320 m) of the laser. It can cause distraction, being brighter than surrounding lights, within 2 miles (3.2 km) of the laser The retrograde ejaculation does NOT EVER go away according to my research. I had the green light done and it appears to be about 80% effective in improving bladder emptying but although I am 58 years old I am somewhat disappointed about the RE even though I'm pretty sure I am done having kids Site it in however you need to but don't expect to use it or a green laser in daylight at any distance beyond 10 meters. Doubtful if the red would go that far effectively. And when you zero, smooth-surfaced, light colored targets are better as they reflect light opposed to dark colors which absorb light A green laser of comparable quality to a red laser will usually cost about double. This is because of the more advanced technology required to make them, and how challenging it is to make a green laser that can withstand the shock from recoil. The tech in a green laser is far more delicate than a red laser, so they are not quite as tough
