Laser Emitter 5mW 5V

The Laser Emitter 5mW 5V is a low-power laser diode emitter with a 5 mW output that runs from a 5 V supply. It produces a narrow beam that is useful for pointers, alignment guides and beam-break alarms, and it is easy to power from a 5 V rail or switch from a microcontroller in electronics and robotics projects.

Laser Emitter 5mW 5V Specifications

• Output power: 5 mW
• Operating voltage: 5 V DC
• Type: laser diode emitter
• Control: on and off by switching its supply, for example with an NPN transistor or MOSFET driven from a digital pin

Laser Emitter 5mW 5V Applications

• Laser tripwire and security alarms with an LDR or photodiode
• Pointers and alignment guides for drilling, cutting and assembly
• Beam-break detection for counters and gates
• Optics experiments on reflection and diffraction
• Robotics and STEM demonstrations

What's in the Box

• 1 × 5 mW 5 V laser emitter

Tip: Never look into the beam or point it at people, animals or shiny surfaces; even a 5 mW laser can damage the eyes. Check the positive and negative connections before powering it, as reversing the supply can destroy the laser diode.
