1: Pay attention to the safety of the laser battery to prevent other people from disassembling the electric power battery and causing short-circuit combustion or battery explosion accidents.
2: The principle of laser emission and the particularity of the production process determine that the laser has the characteristics that ordinary light does not have: three good (good monochromaticity, good coherence, and good directivity) and high (high brightness).
3: Mainly used in laser toys, various spirit levels, ground wires, etc.
Making an electronic pointer pen: When the teacher is giving a lecture, he uses a laser to project the dots to ask the students to observe and think.
Electronic spirit level: let the motor drive the bald head to rotate or twist, project into a straight line on the wall, for horizontal reference when decorating or posting new year pictures.
Miniature liquid crystal projection: Remove the condenser lens and let the laser light pass through the controllable LCD screen to produce a clear projection on the wall.
Long-distance laser monitor: Let the laser light shine on the glass of the room being overheard, then receive the laser beam reflected by the glass, and detect the vibration of the glass to restore the sound of the room.
Long-distance light control anti-theft alarm: Install a laser emitting tube and a photoresistor at one corner of the fish pond or watermelon field to be protected, and install mirrors at the other three corners to form a protective area.
Long-distance laser wireless communication: a pair of laser transceivers are used to face each other on two distant roofs, and a single-chip serial communication protocol can be used to send and receive files and even network.
The laser head is composed of a light emitting die, a condenser lens and a 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 it has been glued with strong glue.
Well, users can work by connecting 3V DC power.
3V laser head parameters (Cable length: 4.5CM)
The laser emission principle and the particularity of the production process determine that the laser has characteristics that ordinary light does not have: three good (good monochromaticity, good coherence, good directionality) and one high (high brightness).
