See what’s really there with trevista DOME!

Cognex trevista DOME is a patented illumination concept with a unique shape-from-shading* technology. It is particularly suitable for inspection tasks on demanding surfaces.

- Perfect image quality for evaluating the finest topographical defects
- Patented 2½D Shape-from-Shading process with 3D inspection quality
- Optimised for inline inspection in industrial environments with high part throughputs

Application examples:

- Automated inspection system with trevista dome, which enables 100% inspection for function-critical defects in the µm range. The robust high-speed approach is perfect for integration into the existing production process.
- Single and cluster defects of the motor piston shell surface are detected and classified on the graphite layer as well as on metallic surface
- Bipolar plate fuel cell: typical punching defects such as waviness, scratches, kinks and material inclusions are detected on coated and/or uncoated bipolar plates

All features and advantages:


- trevista DOME is the “state-of-the-art technology” in the shape-from-shading process
- Sensor technology perfect for surface inspection in industrial environments
- Realisation of cost-effective inspection systems without time-consuming illumination design and costly re-parameterisation – for maximum inspection reliability
- Enables 100% inspection with high part throughput – short amortisation
- Reliable detection of bad parts based on the topography information obtained in the μm range for maximum inspection stability
- Minimisation of pseudo-rejects
- Reproducible result images ensure production reliability
- Stable inspection even with varying degrees of gloss and fluctuating brightness properties of the surface
- Robust and maintenance-free, no readjustment necessary
- High precision
- Enormous light output
- Perfect physical arrangement
- Complex technology simply integrated by AIT Goehner
