A bright green light with a beam so strong it is actually visible in the dark. That’s what you get with the 532 nm Green Laser Pointer. This pointer is about 50 times brighter than a red laser pointer operating at 650 nm wavelength. Its unusual color will also stand out better than a red dot. The green laser beam dot can be seen at much greater distances than with a red laser pointer. Because the beam is visible in darkness, it will be useful in other applications as well, like pointing out stars and constellations in the night sky or for diffraction experiments. The 532 nm Class IIIa light is 6″ long x 1/2″ dia, with (2) “AAA” batteries (included). Also includes an attractive high quality case suitable for giving as a gift. Or just for safely storing your new coolest toy.
