Surface Roughness Data for Calcite and Quartz Samples Polished with Various Grit Sizes

This dataset contains raw surface roughness data for calcite and quartz samples polished with different grit sizes (30, 100, 400, and 1000). The data was acquired using confocal laser microscopy at 50x magnification with 10% overlap stitching and 5x5 tiling. The vertical resolution is 10 nanometers, and the lateral resolution is 20 nanometers. The Z-height data is reported in microns. The dataset consists of 8 files, each corresponding to a specific mineral and polishing grit size: Calcite: 30, 100, 400, 1000 grit Quartz: 30, 100, 400, 1000 grit Each file contains high-resolution surface topography data, providing detailed information on the surface roughness of the samples. File Format: The data is stored in .mat files, which can be read using MATLAB or other compatible software. Metadata: Measurement technique: Confocal laser microscopy Magnification: 50x Stitching overlap: 10% Tiling: 5x5 Vertical resolution: 10 nanometers Lateral resolution: 20 nanometers Z-height units: microns This dataset is suitable for researchers interested in surface roughness, materials science, and tribology.
