TRV Corp maintains comprehensive in-house inspection capabilities to verify dimensional accuracy, geometric tolerance, and surface quality across all manufactured components. Our quality laboratory combines automated vision systems with traditional precision instruments for complete measurement coverage.

Micro-Vu Vertex Automated Vision Systems

The systems include InSpec Metrology Software, a programmable optical zoom, 3xdigital zoom, non-linear stage compensation, non-linear optics compensation, and advanced LED lighting. InSpec Metrology Software provides point-and-click simplicity, proprietary edge detection, advanced lighting control and calibration, multi-sensor integration, automated calibrations, and a clear display of measurement data and tolerances.
