for high-precision 3D metrology
Overview of features and benefits
- Easily integrated in lab, shop, or fully-automated industrial inspection setups
Modular and customizable to your criteria
- 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 set of user-defined GD&T callouts
- 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 industry-standard formats
- Adaptable to harsh environments
- No consumables are needed: The optical galvo scanner does not come in contact with the measured surface, and therefore does not wear out like contact probes.

Examples of inspection applications
The SURFACEINSPECT system delivers 3D metrology across multiple industries – both in high-volume production and in research labs. A few examples of applications:
- Dimensions and surface finish of parts made by machining, casting, injection molding, 3D printing, additive manufacturing, welding, brazing, soldering
- Dimensions and thickness of extruded materials – plastics, ceramics, glass – during or after extrusion. Tubing, sheeting, fibres, etc.
- Continuous casting
- Tool maintenance, edge inspection – sharp edges, chamfered edges, bevel edges, filleted edges, miter edges, burr detection
- Protective film thickness in aviation and automotive industries, on consumer products
- Multilayer thickness measurements in the cellphone industry
- Optical: etching and deposition thickness on waveguides
- Semi-conductors: coating on MEMS devices, hybrid circuits, fuel and solar cells; wafer topography, thickness, flatness, defect detection; inspection of thick film photo-resist coating on electronic wafers
- Ophthalmology: inspection of regular or intraocular contact lenses
- Bio-medical: tissue thickness; GD&T and surface finish of orthopedic, ocular, dental, and hearing aid implants; coatings that protect devices from corrosion or patients from complications

- Others: conformal coating, protective tool coating, vacuum chamber coating
Frequently asked questions
How long does it take to scan a surface with SURFACEINSPECT system?
- Scan time depends on the surface area and aspects you need to measure. The SURFACEINSPECT system features a galvo scanner which scans the surface in a raster fashion. The speed of the scan is user-programmable and the SURFACEINSPECT system acquires up to 100,000 measurements per second, or roughly 1 million 3D topography points in 10 seconds. The user selects the lateral sampling distance in X and Y 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 (GD&T) require the least amount of points and can be achieved the fastest. Defect detection requires the most amount of points, of course depending on the size of defect you are looking for.
The following is an example of scanning-time calculation with acquisition speed of 100 kHz, i.e., 100,000 points per second (click table to enlarge).

Can the SURFACEINSPECT system measure parts that are not flat and high-aspect ratio features?
- Yes, depending on the geometry of the features to be scanned. Various curved surfaces and high-aspect ratio features have been scanned. Displacement stages can be added to the setup if required.
Can the SURFACEINSPECT system be used to measure the thickness of a coating?
- 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).
Is the system easy to use?
- Yes. 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 production floor?
- Yes. The system is ideally suited for both lab and shop floor inspection. Inline and robot setups are also supported. The SURFACEINSPECT system can even be used to provide metrology in hostile environments such as extremely hot, cryogenic, or radioactive.
Can the SURFACEINSPECT system give us automated measurements and reports?
Does the light beam of the the SURFACEINSPECT system have to be perfectly perpendicular to the surface to be scanned?
- No. Some surfaces have been scanned with as much as 60 degrees between the light beam and the surface. The maximum scan angle depends on the material and surface characteristics.
