Optical Mirror

Galvanometer Mirror

Galvanometer mirror (Galvo) is a high-precision beam scanning mirror. By rapidly and precisely controlling the angle of the mirror, the propagation direction of the laser can be dynamically changed, enabling rapid scanning or positioning.

Typical Application Areas

Laser Processing

This is the most classic application of scanning mirrors. In laser marking, engraving, cutting, and drilling, the scanning head, composed of X-Y galvanometers, can guide the laser beam to "draw" arbitrary shapes on a plane at high speed and with high precision, greatly improving processing efficiency and accuracy.
Automotive LiDAR

This is a popular application of scanning mirrors in recent years. As a core scanning component, it guides the laser beam to scan the surrounding environment through high-speed vibration, helping autonomous vehicles to perceive complex road conditions more accurately.
Scientific Research and Optical Communication

In biological imaging, quantum optics research, and free-space optical communication, scanning mirrors are also frequently used to quickly and precisely manipulate the direction of the light beam.
