Micro-marking
| This data matrix contains 14 x 14 elements on an area of 100 µm x 100 µm and is used on small parts with a width of Positioned 0.35 mm in the middle. To ensure reproducibility and readability, the height of the focus may only deviate within a range of +/- 15 µm. Since the parts have a manufacturing tolerance of +/-80 µm, the height of each part must be measured and the focus distance adjusted. The process time is 0.3 s including positioning via image processing, measuring the part height, adjusting the focus and lasering the data matrix. Standalone laser devices |  | ||
