1: Pay attention to the safety of the laser battery, and prevent others from disassembling the electric power cell to cause short circuit combustion or battery explosion.
2: The emission principle and the particularity of the production process of the laser determine that the laser has the characteristics that ordinary light does not have: three good (good monochromaticity, good coherence, good directivity) and one high (high brightness).
3: Mainly used for laser toys, various levels, ground wire instruments, etc
Making an electronic pointer pen: When the teacher is giving a lecture, he uses a laser projection point to ask students to observe and think.
Electronic level ruler: let the motor drive the light head to rotate or twist, and project it into a straight line on the wall for horizontal reference when decorating or pasting New Year pictures.
Micro LCD projection: remove the condenser, and let the laser pass through the controllable LCD screen to produce a clear projection on the wall.
Remote laser monitor: let the laser shine on the glass of the eavesdropped room, then receive the laser beam reflected from the glass, detect the vibration of the glass and restore the sound of the room.
Remote light control anti-theft alarm: a protective zone is formed by installing a laser emission tube and a photosensitive resistor on one corner of the fish pond or watermelon field to be protected, and installing a mirror on the other three corners.
Long distance laser wireless communication: use a pair of laser transceiver to face each other on the roof of two far rooms, and use the serial communication protocol of the microcontroller to send and receive files, or even network.
The laser head is composed of three parts: luminous tube core, focusing lens and copper adjustable sleeve. When the laser head is sent to the user, the three parts have been assembled, the lens focal length has been adjusted, and the laser head has been glued with strong glue
OK, users can work after connecting 5V DC power supply.
The life of the laser head is about 3000 hours, as long as it is not artificially damaged, thousands of hours
In the daytime, it is 1 to 5 meters under the sun, and it can be at least 500 meters from the indoor to the outdoor
3V laser head parameters
(Lead wire length: 4.5CM)
The emission principle and the particularity of the production process of the laser determine that the laser has the characteristics that ordinary light does not have: three good (good monochromaticity, good coherence, good directivity) and one high (high brightness).

4.5V laser head laser module laser tube laser diode plastic gyro module red dot
Composition of the product: the laser head consists of three parts: the luminous tube core, the condenser lens, and the sleeve. When the laser head is sent to the user, the three parts have been assembled, the lens focal length has been adjusted, and the lens has been glued with strong glue. The user can work after connecting to the 4.5V DC power supply.
Product description: Under ideal conditions (no dust, smoke, or any barrier), the laser transmission distance is unlimited. When the laser head gives 20MA working current under the condition of high air quality, the transmission distance can reach more than 1KM, and it can be easily seen on objects 500 meters away in cloudy nights; At a relatively close distance, even in the daytime sun, it is clearly visible on the outdoor roads and buildings
Working voltage: 4.5V 51 Resistance working time: quite long (because there is no accurate test)
