1: pay attention to the safety of the laser cell, to prevent others from demolition burning electric power pool cause a short circuit or battery explosion.
2: The principle of laser emission and particularity ge ...neration process determines the laser light with a general do not have the characteristics: namely Miyoshi (color is good, good coherence, direction) a high (high brightness).
3: mainly used in laser toys, all kinds of level meter, instrument, such as ground Making electronic pointer pen: When the teacher lectures, students with a laser projection point drew concept investigation thinking
