Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
An infrared transmitter (IR transmitter) is a basic electronic component that sends invisible infrared light signals for short-range wireless control. It is widely used in daily electronics, smart home devices, and industrial equipment due to its low cost, low power consumption, and stable performance.
