Racing is my favorite general game. Before the experiment, or very need a black head collocation, then need to focus on the game's blue laser point. The laser beam must be carefully fixed to the match head. In this way, it is powerful enough to turn on the light normally. It's an exciting moment, as the green laser designator's suggestion burns quickly in just a few seconds. Lasers are determined by the actual wavelength or frequency of light. In the visible spectrum, green at 532 nm is the brightest laser color for the same output human eye. So when you look at a 200mW laser, green is 7 times brighter than any other color 200mW.
