"It's foreign to our visual system. Little knows the length of the beam. It can be seen for miles. The beam appears to the owner of the laser to be the weather hundreds of feet away. The stars will improve the green. The recommended 5MW green laser designator is 5-10 times brighter than a 5MW red laser because the human eye sees green much better than the same amount of red or blue. Looking at green beams in the sky does not affect night vision. To maintain night vision, do not look directly at laser points on bright surfaces or colors. Welcome to laser pointer store. From now on, we will introduce all kinds of ultra-high power high powered laser Pointers. Wouldn't it be cool if you only had one of those things? Of course, compared with 5MW laser pen, 10MW laser pen, 100mW laser pen and other low power laser pen, the practicability is not strong, less activity scenes, but also has its own advantages. For example, the idol concert does not need the brightness of the light? So 10000MW laser pointer and 5000MW laser pointer are just fine. The laser beam is also much brighter than the low-output one, giving it a more showy atmosphere. Ultra high power laser pointer
