5V laser head laser diode semiconductor laser dot copper tube outer diameter 6MM
Black is negative positive red
Wavelength: 650NM Power: 5MW outside diameter: 6MM
1: pay attention to the safety of the laser cell, to prevent others from demolition burning electric power pool cause a short circuit or battery explosion.
2: The principle of laser emission and particularity generation process determines the laser light with a general do not have the characteristics: namely Miyoshi (color is good, good coherence, direction) a high (high brightness).
3: mainly used in laser toys, all kinds of level meter, instrument, such as ground
Making electronic pointer pen: When the teacher lectures, students with a laser projection point drew concept investigation thinking.
Electronic spirit level: Let motor driven head rotation or twisting, projected in a straight line on the wall for decoration or to post pictures when you do the horizontal reference.
Miniature LCD projector: Remove the condenser, so that the laser can be controlled through the LCD screen, you can produce a clear projection on the wall.
Laser remote listener: the laser is irradiated on a glass room eavesdropping, and then receives the laser beam reflected back to the glass, to detect the vibration of the glass out of the room to the sound reduction.
Remote light control anti-theft alarm: the need to protect the fish pond in the corner or the watermelon fields in the launch tube fitted with laser and light-sensitive resistors, in the other three corners of the mirror mounted on the back to form a protective zone.
Laser distance wireless communication: the use of a pair of laser transmitters and receivers are facing each other in two distant roof, the use of single-chip serial communication protocol you can send and receive files, and even networking.
The laser head by emitting die, condenser lens, adjustable sleeve is composed of three parts copper, when sent to the user, these three parts already assembled, but also adjust the focal length of the lens, and has used strong glue stick
Well, users connected to 5V DC power to work
