Violet lasers belong to those who really love the blue laser tech, and Here violet blue laser's visibility is not that obvious as green laser, red laser or blue laser beam because of the insensitivity of 405nm beam to light, and its beam only becomes relatively bright or visible when it reaches >50mw, but it's visible in ultra dark conditions. We advise you to shoot against the beam when taking the laser photography, while the violet laser beam will be bright and exciting enough.
