This dataset is part of a series showing the surface of an agate stone at each stage of polishing. This is the stone’s surface after the first tumbling pass with 60-grit silicon carbide. The low area is an inclusion of a softer material in the stone. Measured with a Zygo ZeGage Plus, 10x objective, desampled. … Read more

This dataset is part of a series showing the surface of an agate stone at each stage of polishing. This is the stone’s surface after tumbling with 125-grit silicon carbide. The low area is an inclusion of a softer material in the stone. Measured with a Zygo ZeGage Plus, 10x objective, desampled. Data source: Bob … Read more
This dataset is part of a series showing the surface of an agate stone at each stage of polishing. This is the stone’s surface after tumbling with 500 grit aluminum oxide plus plastic pellets. The low area is an inclusion of a softer material in the stone. Measured with a Zygo ZeGage Plus, 10x objective, … Read more
This dataset is part of a series showing the surface of an agate stone at each stage of polishing. This is the stone’s surface after final polishing at 1500 grit. The low area is an inclusion of a softer material in the stone. Measured with a Zygo ZeGage Plus, 10x objective, desampled. Data source: Bob … Read more
This dataset, showing the scales of an orange throated darter, was featured in our blog post, “Surface roughness sheds light on how fish evolve.” It’s a great dataset to try out the Path/Curve Cross-Section tool in OmniSurf3D. Use the tool’s handles to draw a curve along one of the scales. The profile along that curve … Read more
