Product introduction
3V/5V Laser Head Laser Diode
1. Attention should be paid to the safety of laser batteries to prevent others from disassembling them.
Cause short-circuit combustion or battery explosion accident.
2. The principle of laser emission and the particularity of its production process determine that laser has the characteristics different from ordinary light: three good (good monochrome, good coherence, good direction) and one high (high brightness).
3. Mainly used for laser toys, all kinds of levelers, ground wires, etc. 1, electronic level ruler, let the motor drive the bald head to rotate or twist, projecting into a straight line on the wall, for decoration or posting New Year's pictures to do horizontal reference. (2) Micro LCD projection: Remove the concentrator and let the laser pass through the controllable LCD screen, which can produce a clear projection on the wall. (3) Long-range laser monitor: let the laser irradiate on the glass of the pleasant room, and then receive the laser beam reflected back from the glass, detect the vibration of the glass and restore the sound of the room. (4) Long-distance light-controlled anti-theft alarm: a protective zone is formed by installing laser emitter and photoresistor in one corner of a fish pond or watermelon field that needs protection and a mirror in the other three corners. (5) Long-distance laser wireless communication: using a pair of laser transceiver devices facing each other on two distant roofs, using the serial communication protocol of single-chip computer can send and receive files, or even networking. Making electronic whip pen: Teachers use laser projection points to ask students to observe and think when lecturing.
