An optical microscopy (OM) (Olympus BX51) was used for depth measurements based on cross sectional images, an inverted metallograph (Nikon, Epiphot 200) was used based on topological focal length variations, and furthermore the depth measurements were confirmed with a laser profilometer (Model Solarius--AF 2000) and also an optical profiler (Microphotonics).
