-Surface Metrology Basics
Surface metrology involves measuring surface texture, roughness, and topography using contact or non-contact techniques.

3D Stylus Profiler
A 3D stylus profilometer uses a fine stylus to trace the surface of a part and create a 3D topography map. The stylus moves…
-
Capacitance Measurement
Capacitance measurement is a non-contact method to assess surface roughness and other characteristics by measuring the capacitance between a probe and the surface. As the…
-
Confocal Microscopy
Confocal microscopy is a technique for measuring surface texture and shape. In a confocal microscope, pinhole aperture is used to create a single focus…
-
Conformal Sensor Measurement
This type of measurement system uses a soft, high resolution, elastomeric sensor that conforms to the shape of the test surface. The deflection of…
-
Coordinate Measurement Machine (CMM)
A coordinate measuring machine (CMM) provides precise measurement of the dimensions and geometry of physical objects. A probe or sensor detects points on the object’s surface, and…
-
Focus Variation Microscope
A focus variation measurement system has a small depth of focus. during a measurement, the optical system scans vertically. By analyzing data acquired at…
-
Light Scattering
Light scattering techniques use the scattered reflection of light from a surface to infer information about the surface texture, structure, and material properties. Techniques…
-
Phase-shifting Interferometer
A phase measuring interferometer detects the difference in phase between the test and reference legs of a split laser source, enabling measurement of surface…
-
Stylus Profilometry
A stylus profilometer (stylus profiler) determines the shape and roughness of a surface by dragging a fine diamond tip across the sample. The 2D…

White Light Optical Profiling
An optical profilometer (optical 3D surface profiler, coherence-scanning interferometer) is a non-contact instrument for measuring surface texture on precision surfaces. An optical profiler, a…
