The Light Bar Focus operates with sensors, otherwise known as light barriers, that are installed laterally in the enclosure. The processing table will move up if the autofocus on the keyboard of the laser system is activated. As soon as the material that you insert beforehand has passed the light barriers, the upward movement of the table will stop. This means that the focusing stage is complete and that you can proceed with laser processing.
We recommend the Light Bar Focus for flat, opaque materials where the material thickness is unknown.
