Its brightness can be clearly seen at day or night, suitable for security lighting and equipped with high-definition night vision camera function. Lasers are bad for eyes. Do not ventilate at eye lighting. Wear appropriate laser goggles indoors or near the blue laser pointer. Avoid pointing the laser pointer directly at your eyes. Laser irradiation up to 30mW can not be directly on the human body, so as not to cause accidental injury. If the high powered laser pointer feels very hot, stop using it immediately until it cools completely. The best time to use a high-power laser pointer is 1 minute, and then turn it on after 5 minutes of cooling. It can prevent excessive aging of laser pointer or damage of laser diode due to overheating. These indications protect the laser designator for longer service life.
