xcluma 3V laser head laser diode dotted 6MM outer diameter

Description

"Specifications:Output Power : 5mwWavelength : 650nmWorking Voltage : 3~5VWorking Temperature : +10 ~ +40CLaser Shape：Point / Cross / LineDescription3V laser head laser diode semiconductor laser dot copper tube outer diameter 6MM Black is negative positive red Wavelength: 650NM Power: 5MW outside diameter: 6MMPay 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.The laser emission principle 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, good directionality) and one high (high brightness).Mainly used for laser toys, various spirit levels, ground level instruments, etc. Making an electronic pointer: When the teacher is giving a lecture, the laser projection point is used to draw students to observe and think.Electronic level: Let the motor drive the bald head to rotate or twist, and project it into a straight line on the wall for horizontal reference when decorating or posting New Year pictures.Mini LCD 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 shine on the glass of the room being eavesdropped, and then receive the laser beam reflected back by the glass, and detect the vibration of the glass to restore the sound of the room.Long-distance laser wireless communication: use a pair of laser transceivers to face each other on the two farther roofs, and use the serial communication protocol of the single-chip microcomputer to send and receive files, and even network.The laser head is compose
