Interesting Facts about Green Laser Pointers

It's been a while since I posted some info on green laser pointers, so here's some things you might find interesting about it:

• Green laser pointers are up to 60-70 times more powerful than red laser pointers. This is partly because the wavelength of the light (532 nm) makes the light green, which is naturally brighter than red light.
• The maximum range of green laser pointers in the dark is anywhere from 12,000-25,000 feet. It depends on the make of the laser, the power output (the maximum required by the FDA is 5 mw, but you can get OEM green lasers for much more power, in some cases up to 30 or 40 mw), and the quality of the laser. Some companies offer military grade green laser pointers. These kinds will surely have a range of 20,000 plus feet!
• Most green laser pointers will have an operating time of more than 3000 hrs. That leaves plenty of time for star gazing and for astonomy enthusiasts to use their laser! Usually the green lasers will require 2 AAA bateries, so they're easy to replace.
