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

You’ve likely seen a comparator strip that includes samples of common machined surfaces. We have similar examples of machining operations in this library as well. This dataset is the turned surface of a cylindrical shaft. Remove the cylindrical form (Analysis Settings > Geometry/Form > Cylinder) to view the underlying surface texture. Click the Profile toolbar … Read more
You’ve likely seen a comparator strip that includes samples of common machined surfaces. We have similar examples of common machining operations in this library as well. This dataset is the outside diameter shaft with surface produced by grinding. Remove the cylindrical form (Analysis Settings > Geometry/Form > Cylinder) to reveal the underlying surface texture. Double-click … Read more
This is a “Lightning” connector on an Apple iPhone charging cable. The data includes an image overlay, which you can toggle on and off using the Camera toolbar icon. Use the Crop tool’s Angle feature (Analysis > Data Crop Tool) to rotate the data, then zoom in on the connection pads and use the cross-section … Read more
This is the leather surface of a wallet. It’s a nice example of longer wavelength surface texture—something akin to the orange peel on a painted surface. It’s also a good example of how a robust short filter can be your best friend. This data includes some spiky noise that is much “taller” than the surface … Read more
This dataset shows a dimple on a Titleist Pro V1 golf ball. The logo printing is just barely visible in the dimple. We can highlight the printing a little more by applying a 4th-order polynomial fit (Analysis Settings > Geometry/Form > Polynomial, with “4” as the x-order and y-order values). Filtering will bring out the … Read more
