Defect detection & hidden corrosion: see beyond the surface
Unveiling the Invisible with Terahertz Technology
Defects hidden beneath coatings are a critical challenge in industries where safety, durability, and quality are non-negotiable. Corrosion, delamination, voids, and adhesion failures can go unnoticed until they compromise performance, leading to costly repairs and safety risks.
At das-Nano, we bring a game-changing solution: NOTUS, powered by terahertz waves, a breakthrough in non-destructive testing (NDT). Unlike traditional inspection methods, NOTUS sees beyond the surface, detecting defects and corrosion in metals, composites, and multilayer coatingsāwith precision no other technology can match.
Why NOTUS? Advanced inspection for demanding industries
- 100% non-destructive & contactless
Inspections without damaging the material. - Detects corrosion & subsurface defects
Identifies what other methods miss. - Works on all materials
Metals (steel, aluminum, titanium) & composites (carbon, glass fiber). - Unmatched precision
Measures individual coating layers with micron-level accuracy. - Applicable across sectors
Aeronautics, automotive, energy, marine, and beyond.
Beyond visual & traditional Inspections

Visual Inspections are not enough
Surface assessments often miss what lies beneath. Environmental conditions, lighting, and human error make them unreliable.

Ultrasound & eddy currents have limits
These methods measure only single layers, failing to analyze full multilayer structures and hidden defects.

Inefficient & costly maintenance
Missed defects lead to unplanned downtime, structural failures, and rework costs. Early detection means proactive maintenance and reduced costs.
Industries that trust our defect detection technology
At our core, we prioritize our customers’ satisfaction, ensuring they feel valued and deeply committed to their projects. Building meaningful connections, we treat every customer like a friend, going the extra mile to ensure successful results and delivering top-quality sheet metal and fabrication solutions.
