Auto - Focusing System Laser Ranging Sensor With 200mm Measuring Range , GHC-1200

product description:
Autofocus system includes laser ranging sensor, communication board.
A special version of the ECZAD software is required.
 

working principle:
Laser Marking AF system is the use of distance sensor to galvanometer to the distance between the workpiece marking, and then dynamically adjust the Z-axis laser marking machine height, it is always marked in the time with the marking workpiece to maintain a fixed distance (focal length) .
EZCAD software is to get the distance value of the sensor, and then calculate the distance value and set the distance value (need to set the focal length position in advance) in the process of looking for the focal length of the Z axis, constantly corrected distance difference To achieve the function of auto-focus.
