Paint Coating Thickness Measurement
TeraNIM™ – Automotive measures multi-layer paint coating thickness on metal or plastics.
- In a single scan, all layer’s thicknesses can be measured automatically.
- Accurately measures individual layers: primer, basecoat, and clear coat—even on curved surfaces.
- Seamlessly integrates with robotic arms and production lines for continuous, contactless inspection.
- Identifies hidden defects such as poor adhesion or air pockets that traditional methods can’t detect
How It Works: Converting THz Pulse Delay into Layer Thickness
A short THz pulse is reflected at each dielectric interface; time delay between echoes maps to layer thickness after calibration.
- Calibrate: Use refractive index / reference coupons to map time to thickness
- Scan: Acquire reflected THz waveform at each measurement point
- Detect THz Reflections: Find pulse arrivals from coating interfaces
- Report: Layer-wise thickness, trend and QC result exported digitally
Software GUI
- Real-Time Measurements
- Load Master Data
- Single or Multi-layerthickness measurements
- One-Time Calibration
- Suitable for robot integration
- Built for single operator GUI
