This data shows the grooves of a stereo, vinyl LP record. The z-axis (heights) in surface data are commonly exaggerated in order to show detail. In OmniSurf3D choose View > Make 1:1 Aspect Ratio to see a truer representation of the slope of the groove walls. The song, by the way, is from an Arthur … Read more
20-pound, uncoated, multi-purpose printer paper. Compare the image above to the image of tissue paper, also in this library: They look very similar, right? But if you look at the z-axes of both plots, the vertical scale of the tissue paper is almost 10 times larger.When you display basic height parameters such as Sa, the … Read more
This is a measurement from the cylinder bore of a diesel engine. The surface is plateau honed cast iron and there are pores and graphite “pull-outs” present in the surface. Removing the cylindrical shape (Analysis Settings > Geometry/Form > Cylinder) reveals the cross-hatch honing pattern as well as the porosity. Areal/3D data is important for … Read more
This is a molded, aspheric lens. When working with lenses the circular cropping tool in OmniSurf3D comes in handy. Choose Analysis >Data Cropping Tool, then check the Crop to Circle/Ellipse box. You can also click the Exclude Center box to occlude the central portion of the data. Holding down the “Ctrl” key while dragging a … Read more
This is an example of plasma coated cylinder bore. The plasma porosity can be seen, as well as the cross-hatch pattern from the subsequent honing operations. In Omnisurf3D you can use the Pit/Porosity Analysis (Tools > Pit/porosity Analysis) to explore the depths of the pores across the surface. Click and drag the blue, horizontal line … Read more
This series of data captures a US one cent coin with two different systems, at 3 resolutions: PennyBack-Lincoln, this dataset, measured with a Zygo NewView 8300 at 10x. PennyBack-LincolnAndPillars, measured with a Zygo NewView 8300 at 2.75x. Penny-All shows the entire back of the coin, measured with a Keyence VR-3100 at 12x. We featured this … Read more
