800 nm laser pointer

800 nm laser pointer is infrared laser, it produces 800 nm laser. The 800 nm laser pointer is invisible laser, the 800 nm laser beam can't be seen by human eyes. However you can see the 800 nm laser dot, while the 800 nm laser shoots on some targets. You need to look at it carefully. We usually call 800 nm laser pointer to 808 nm laser pointer. The beam size of some high power 800 nm laser pointer is about 1 cm across when it leaves the laser, and even with that high peak power, you only start to cause some serious damage when you focus it down to a mm or less
