for high-precision 3D metrology of edge breaks/edge radiuses
Overview of features and benefits
- Easily integrated in lab, shop, or fully-automated industrial inspection setups
- Reduces inspection cycle time: the non-contact optical scanner (or probe, depending on the setup) obtains up to 100,000 measurements per second. Each measurement represents a 3D topographic point.
- Flexible options for evaluating inspected parts: measured features can be compared to CAD drawings or to a user-defined set of locations, nominals, and tolerances
- Simple scan definition and execution: The scanning sequence is defined once by teaching the system with a joystick. The scanning sequence can later be executed with the push of a button.
- Time-saving automated reporting:Following a scan, go-no-go reports can be produced and results logged in a manner compatible with industry-standard mechanisms.
- Adaptable to harsh environments
- No consumables are needed: Optical probes do not come in contact with the measured samples, and therefore do not wear out like contact probes. Accidental damage is rare−probes are designed to be rugged.
3D metrology and imaging of edges for industry and R&D

Typical measurements on edges
- Full geometry, diameter, circularity, cylindricity, taper, runout, etc.
- Deviation from CAD model
- High-aspect-ratio features: teeth, undercuts, steps, grooves, threads, channels, sharp edges, cross-holes
- Volume loss: surface wear or other damage
- Defects: corrosion, pitting, cracking, denting, scratching, porosity
- Surface roughness: linear or area roughness
- Thickness of semi-transparent coating on edge surfaces: single-layer or multilayer films

Frequently asked questions
How long does it take to scan an edge with EdgeInspect?
- Scan time of an edge depends on the area size and aspects you need to measure. The EdgeInspect acquires up to 100,000 measurements per second, which represents roughly 1 million 3D topography points in 10 seconds. The user selects the lateral sampling distance in longitudinal and circumferential directions and the size of the area to be scanned, which together determine the number of points that will be acquired and the time that the scan will take.
- In general, dimensional measurements (for GD&T) require the least amount of points and can be achieved the fastest. Roughness callouts may take 3 to 4 seconds each. Defect detection requires the most amount of points, of course depending on the size of defect you are looking for.
- For help with estimating the time required to scan your part, please contact us.
Can the EdgeInspect be used to measure the thickness of a coating on edges?
- Yes, if the coating is semi-transparent to infrared light and has optical thickness of 20 µm or higher (optical thickness = physical thickness * index of refraction).
How about inside corners – i.e. does the EdgeInspect measure inside edges in concave forms?
- The EdgeInspect can measure both inside corner edges as well as outside edges. In both cases, it can delivers high-precision diameter, contour, profile, and coating (or material) thickness measurements.
Can EdgeInspect measure very sharp edges?
- Yes, depending on the geometry of the features to be scanned. Various radius of curvatures as small as 6 µm have been scanned.
Is the system easy to use?
- The scanning sequence (recipe) can be programmed with a joystick and can be recalled at later times with the push of a button.
Is the system able to work right on the production floor?
- The system is ideally suited for both lab and shop floor inspection. Inline and robot setups are also supported. The EdgeInspect can even be used to provide metrology in hostile environments such as extremely hot, cryogenic, or radioactive.
Can SurfaceInspect give us automated measurements and reports?
