As manufacturers of glass products continue to learn about the ease of use and cost savings that result when replacing labeling, etching, or blasting operations with CO₂ laser marking, they are finding more and more products to mark, label and even decorate. Today, it is common to find window panes, automotive glass, CRT displays, and glass bottles being laser marked with serial numbers, part numbers, 1D and 2D codes, corporate logos, and decorative artwork.

The photo shows an example of a decorative glass bottle marked using an FH Series marking head. We used a 125 mm focusing optic that produced a 180-micron (0.007”) spot with a 3 mm (0.118”) depth of focus. At a galvanometer velocity of 18 inches per second (IPS) and a power of 19 watts, we marked the 20 mm by 13 mm (0.80” x 0.52”) image in an overall cycle time of 0.94 seconds.
