Laser Gauge & Profile Inspection
Use Sciemetric’s process monitoring system for laser profile inspection to detect surface defects in real-time. Sciemetric provides accurate, effective profile inspection so manufacturers can trust the quality of their parts and identify the root cause of defects when issues occur.
Real-time monitoring and advanced analysis of profile inspection data
Profile inspection provides a simple, cost-effective alternative to machine vision systems to verify the presence of components, identify surface defects, detect incorrect assemblies or monitor planarity in flat parts. The use of Sciemetric’s digital process signature technology provides a picture of each part along with multiple points of measurement to deliver repeatable, fast and accurate pass/fail inspection.
What can be monitored:
- Part or seal presence
- Part or seal location and assembly flatness and verification
- Stack up tolerances
- Surface finish
Faults that can be determined:
- Improper assembly
- Missing components
- Defective components or stack ups
Use Sciemetric’s sigPOD to monitor laser gauge and profile inspections
Sciemetric’s profile monitoring solutions uses a sigPOD to monitor and measure dimensional data from a laser profiler, probe, camera, air pneumatic gauging device, or other displacement sensor/encoder, capturing a full digital signature (waveform). The sigPOD enables analysis of specific zones on a part, flexible measurement of parameters and statistics for smoothing the signals. Critical dimensions are set and measured/compared to predefined specification limits

The sigPOD simplifies complex measurements
Using Sciemetric’s technology, two or more dimensional measurements can be used to calculate new measurements, such as the slope of a surface, or the depth of a bore, for example. For more complex dimensions that can’t be represented by a single measurement, the data can be represented as a signature and evaluated against a previously measured nominal or master signature for conformance.
Ultimate visibility into your profile inspection using Sciemetric’s waveform technology
Sciemetric’s digital process signature (waveform) technology records more datapoints than any other system, and visualizes the data as a waveform that mimics the part being monitored, offering a clear, visual way of verifying dimensionally complex parts during a laser gauge or profile inspection.

Our technology provides real-time profiling and analysis in non-contact and contact profile inspection applications. Both non-contact and contact profile testing are reliable methods of contour measurement and defect detection—the ideal approach will depend on the specific application.
Contact Profile Inspection
Contact profile testing uses probes or similar instruments to scan the surface of a part and find potential defects. Contact profiling is a better option when measuring transparent surfaces, or other surfaces that are problematic for non-contact devices. This method of profile testing is significantly slower in the collection of data points but provides a high level of accuracy. When measuring complex parts, it is critical to keep assumptions realistic, so your compensations are accurate.
Tools used for contact profile inspections:
- Hand tools like dial indicators, digital calipers, micrometers
- Contact probes, or coordinate measurement machines (CMMs)
Non-Contact Profile Inspection
Non-contact inspection uses a profile laser or similar technology to test a high volume of parts and components in an automated production line. Using a non-contact profiling method is ideal for electronics and other components easily damaged using contact testing methods and overall requires less maintenance and calibration. Another benefit is that non-contact profile testing provides faster surface measurement, allowing for high sampling rates.
Tools used for contact profile inspections:
- Pneumatic gauging, or air gauging
- Optical and vision-based systems, including lights, lenses and cameras
- Light-based systems using LEF or laser scanners

Assembly verification for heavy equipment OEM
A manufacturer of heavy equipment was experiencing issues with a major assembly and required an in-process test to detect improper assembly, missing components and component defects. Using a single 2D scanning and image laser, Sciemetric collected the profile signatures for the part providing a reliable, real-time means to verify bearing seal part/seal presence, part/seal location and assembly flatness, and stack-up tolerances.
Precision finishing for advanced semiconductors
A manufacturer of polishing pads used in the production of advanced semiconductors needed to verify the grooves on the grinding edges of these pads met spec for depth and spacing. Any imperfection can lead to expensive quality meltdowns in the field. Sciemetric delivered a laser profiling system to map the contours of the grinding surface. Sciemetric’s analysis software then identified any non-uniform surface characteristics. This solution boosted product quality and demonstrated robust quality assurance to their customers.
