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: good monochromaticity, good coherence, good directivity, and high brightness.

★ Application ★  

• Mainly used for laser toys, various levels, ground wires, etc.

• Making an electronic pointer pen: During the teacher's lecture, use a laser projection point to encourage students to observe and think.

• Electronic level ruler: Let the motor drive the bald head to rotate or twist, projecting it into a straight line on the wall, for horizontal reference when decorating or posting New Year pictures.

• Micro LCD projection: Remove the condenser and allow the laser to pass through the controllable LCD screen, resulting in a clear projection on the wall.

• Remote laser monitor: irradiate the laser on the glass of the room being eavesdropped, then receive the laser beam reflected back 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 photoresistor on one corner of the fish pond or watermelon field to be protected, and installing reverse mirrors on the other three corners.

• Remote laser wireless communication: By using a pair of laser transceiver devices facing each other on two distant rooftops, the serial communication protocol of a microcontroller can be used to send and receive files, and even connect to the internet.

♥ Precautions for Use (Required for Buyers) ♥ 

1. The laser should never be directed towards one's own or others' eyes at any time, as there is a possibility of mistakenly turning on the laser even when it is turned off.

2. The laser cannot shine on any reflective or smooth surface. The laser has excellent reflectivity, and when it shines on the reflective surface, it will produce reflection. If it happens to hit the eyes of a person, it can cause injury.

3. The laser is not a toy and should not be used by children, individuals with intellectual disabilities, or those who are not familiar with the characteristics of the laser. In such cases, it can easily cause harm.

4. When using a laser, special goggles should be worn, which is particularly important for invisible lasers.

5. The laser should not be directed towards vehicles, airplanes, or other vehicles with passengers.

6. Pay attention to the safety of the laser battery to prevent accidents such as short circuit combustion or battery explosion caused by others disassembling the battery.
