infrared beam
Invisible light path
An infrared beam is a focused stream of light at wavelengths just beyond what the human eye can see.
Infrared beams power remote controls, trigger automatic doors and security systems, and enable night-vision devices.
When something breaks the beam, it activates a sensor: The infrared beam detected motion at the entrance.
