Experimental principle

Scanning galvanometer is to make the laser beam incident on the mirror, and use the computer to control the reflection angle of the mirror to achieve the deflection of the laser beam: the laser beam is incident on the first reflecting lens (X axis), and the deflection of the scanning motor drives the X axis The lens rotates to form a position scan in the X axis direction; the light reflected from the X lens enters the second mirror (Y axis) of the reflection lens, and the rotation of the second motor forms a position scan in the Y axis direction to complete the Scan on the plane.

Instrument characteristics

• Modular design and faster installation

• Multi-angle (up, down, left, right, and tilt), high-precision adjustment device

• Visualized light path

• High-speed and stable scanning galvanometer

The scanning speed is stable and adjustable within 0-5000mm / s, which can continuously and steadily scan and output the graphic you designed.

• Visible working status, remote shutdown function of any axis scanner

The driver includes laser power status indicator, X-axis and Y-axis working status indicator, X-axis and Y-axis can be independently controlled remotely, and is equipped with status indicator.
