Figure 1
Optical micrographs of 4 laser-processed PET samples with increasing spacing between the parallel laser processing lines. (a) 300 μm; (b) 400 μm; (c) 500 μm; (d) 600 μm. All samples have been processed at 15% power and a scanning speed of 200 mm/s. The insets are CCI surface maps that have been set to the same scale, and horizontally the scale bar is equal to 200 μm.
