Surface Roughness Measurement Using 3D Optical Profiler

Surface roughness was evaluated using a three-dimensional high-resolution non-contact optical profiler (Contour GT-K 3D Optical Microscope, Bruker, Billerica, MA, USA). The samples were scanned at 20× magnification, at a scan speed of 1× and threshold of 5% [26 (link)]. The software Vision 64 (Bruker, Billerica, MA, USA) was used for the analysis and graphical output, and the average of three scans for every sample was taken [25 (link)]. The average surface roughness (Ra) was reported as the arithmetical mean of roughness profile [26 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
