Before You Send a Sample
What materials can TeraNIM inspect?
TeraNIM is primarily applied to suitable dielectric and low-loss materials such as polymers, coatings, FRP/GFRP structures and other application-specific non-metallic systems. Feasibility depends on absorption, thickness, interfaces, geometry and the required inspection output.
Can TeraNIM measure individual layers in a multilayer coating?
Potentially yes when distinct interface reflections can be resolved with sufficient THz contrast and signal-to-noise ratio. The coating stack should be calibrated and validated using representative reference samples.
Is THz NDT suitable for CFRP and other composites?
THz reflection methods can be useful for suitable coatings, interfaces and low-density structures associated with composite components. CFRP architecture, fibre orientation, conductivity and the exact inspection target can influence feasibility.
Can TeraNIM be used for university research?
Yes. The system can support applied research in material inspection, layer analysis, THz imaging, NDT algorithms, automation and application development without requiring the research group to build the complete THz instrument from components.
Can TeraNIM integrate with a scanner, robot or cobot?
Yes, supported configurations can integrate the THz probe with motorized scanners, robots or cobots for repeatable positioning, spatial mapping and automation-oriented development.
How do I know whether my sample is measurable with THz?
The recommended first step is a sample-feasibility study. TeraLumen can evaluate the material, layer stack, geometry, thickness range and required output before proposing a measurement configuration.
Have a material, coating or defect problem for THz?
Send the material details, approximate thickness, inspection objective and sample geometry. Start with feasibility before deciding the final TeraNIM configuration.
