Optimizing a Cantilever Measurement System towards High Speed, Nonreactive Contact-Resonance-Profilometry (Data)
<p>Raw data, scripts and figures used for the article "Optimizing a Cantilever Measurement System towards High Speed, Nonreactive Contact-Resonance-Profilometry", published in <em>Proceedings </em>on 21 Nov 2018.</p> <p>The data/scripts can be opened/executed by the software "Matlab"</p>
Optical profilometry of the surface of debris catchers used in laser-plasma experiments at ELI-NP
<h3>3D area scans were performed using the 3D Optical Profilometer Bruker ContourX-100.</h3> <p><strong>Method: </strong>The setup consisted of 5x Objective, .55x field of view, 100um back scan and forward scan, and a threshold value of 2% (this threshold means that any height variation that is more than 2% of the standard deviation away from the average will be considered significant). This is considered a lenient threshold that would include a lot of noise, but given the sharpness of the features in the sample and the steep wall angles, a higher threshold value excluded too much of the features. Stitching areas were approx. 15mm x 12mm in size consisting of 20+ individual measurements, with a 20% overlap between scans. The area was chosen to include all areas of ablation visible. Data fill was used to approximate missing data in areas of high damage using the software provided data fill algorithm on Vision64 Software.</p> <p><strong>Results:</strong> Data fill was considerable and introduces a lot of uncertainty. The samples are inherently rough and difficult to measure with optical techniques, so no filtering was applied. The depth of ablation areas had poor data acquisition, consequently the step profilometer was considered for more accurate measurements.</p> <p><strong>Note:</strong> The files can be opened with free tools such as <a title="PROFILMONLINE" href="https://www.profilmonline.com/" target="_blank" rel="noopener">https://www.profilmonline.com/</a> . </p> <p> </p> <h3>Surface profile was performed with Dektak Pro Stylus Profilometer</h3> <p><strong>Method:</strong> The setup consisted of Stylus 2um diameter, 10mm length, Stylus force 10mg, resolution longitudinal 0.555um/pt, resolution quoted as sub 100nm in height. Data was averaged over 5 scans.</p> <p><strong>Results:</strong> Stylus radius of 2um may smooth out the sharpest features. Debris and ablation seem to be immovable and adhered to the substrate such that the probe would not change the substrate during measurement. Multiple measurements were taken and an average of ablation depth was estimated at 10um.</p>
