Laser Marking in the third dimension
01.09.2010
With traditional laser marking, two mirrors direct the laser beam to mark letters, logos and symbols on a flat surface. This is comparable to writing or drawing on a piece of paper.
To function, the laser beam has to be focused on the surface being marked, i.e. it can only move in the direction of the x- and y-axis.
If, however, you wish to mark an object that is not flat, but rather whose surface is curved or irregularly shaped, the distance between the laser head and the marking area varies. In this case, the laser beam's focal point does not always intersect with the surface being marked, which results in poor marking or no marking at all.
With its new LP-Z Laser Marker, Panasonic now offers a solution for marking such surfaces. The laser automatically compensates for variations in height of up to 50mm by adjusting the focal point.
This function can dramatically increase marking quality for large surface areas or multiple objects within a range of 330mm x 330mm. Since the distance from where the laser beam exits the laser head to the center of the marking area is shorter than that to the corners, the LP-Z Laser Marker can also compensate for this difference.
