1: Pay attention to the safety of the laser battery to prevent others from disassembling the electrical power pool to cause short-circuit combustion or battery explosion accidents.
2: The laser emission principle and the particularity of the production process determines that the laser has the characteristics that the ordinary light does not have: that is, the three good (good monochromaticity, good coherence, good direction) a high (high brightness).

3: Mainly used for laser toys, various levels, ground instruments and so on
Make an electronic pointer pen: When the teacher lectures, use a laser to project points to remind students to observe and think.

Electronic level: Let the motor drive the head to rotate or twist, projected into a straight line on the wall, for decoration or Posting New Year pictures to do horizontal reference.

Micro LCD projection: Remove the condenser, let the laser through the controlled LCD screen, can create a clear projection on the wall.

Remote laser monitor: Let the laser shine on the glass of the room to be overheard, and then receive the laser beam reflected back by the glass, detect the vibration of the glass to restore the sound of the room.

Remote light control anti-theft alarm: In the need to protect the fish pond or watermelon field on the corner of the laser emission tube and photoresistor, in the other three corners of the mirror, to form a protection area.

Remote laser wireless communication: The use of a pair of laser transceiver devices in two distant roofs against each other, the use of single-chip serial communication protocol can send and receive files, and even networking.


The laser head consists of three parts: a light emitting tube core, a condenser lens and a copper adjustable sleeve. The three parts have been assembled, the lens focal length has been adjusted, and the laser head has been glued with strong glue

Ok, the user can connect the 5V DC power supply to work.
The life of the laser head is about 3,000 hours, as long as it is not man-made damage, thousands of hours

During the day, from 1 to 5 meters in the sun, you can go anywhere inside and at least 500 meters outside

The particularity of laser emission principle and production process determines that laser has the characteristics that ordinary light does not have: namely, three good (good monochromaticity, good coherence, good direction) and high (high brightness).

The red line is positive, the blue line is negative
