1:Pay attention to the safety of the laser battery to prevent others from disassembling the battery caused by short-circuit combustion or battery explosion.
2: The laser emission principle and the special characteristics of the generation process determines the laser with ordinary light does not have the characteristics: that is, three good (monochromatic, coherent, directional good) a high (high brightness).

3:Mainly used for laser toys, all kinds of level meter, geodesic meter, etc.
Production of electronic whip pen: the teacher lectures, with laser projection points to students to observe and think.

4. Electronic level: let the motor drive the optical head rotation or twist, projected into a straight line on the wall, for decoration or posting of New Year's Eve to do level reference.

5. Miniature LCD Projection: Remove the condenser mirror and allow the laser to pass through the controllable LCD screen, which can produce a clear projection on the wall.

6. Long-range laser listener: let the laser shine on the glass of the room being eavesdropped on, and then receive the laser beam reflected back from the glass, and detect the vibration of the glass to restore the sound of the room.

7. Long-range light-controlled anti-theft alarm: in the need to protect the fish pond or watermelon field in one corner of the laser tube and photoresistor, in the other three corners of the mirror on the opposite side, the formation of a protective zone.

8. Long-distance laser wireless communication: the use of a pair of laser transceiver devices were in two farther away from each other on the roof, the use of microcontroller serial communication protocols can send and receive documents, and even networking.

9. The laser head by the light-emitting tube core, focusing lens, copper adjustable sleeve composed of three parts, sent to the user, these three parts have been assembled, lens focal length is also adjusted, and has been glued with strong adhesive, the user can work by connecting the 5V/3V DC power supply.

Caution:

This component is sensitive to static electricity, without good anti-static measures, please do not use your hands to directly contact the body of the laser tube, in addition, this product must have a qualified drive circuit to work properly, different power voltage is the same, but the working current is different, the circuit of the tube drive current needs to be controlled within a safe range, otherwise it will affect the life.
