UV applications
In production, UV radiation is a tool, a process variable and a test variable at once: it cures coatings and adhesives, cleans and activates surfaces, inactivates micro-organisms, ages materials under controlled conditions and makes defects visible in inspection. This section sorts the methods by their task – UV as a tool, UV as a test quantity, UV in moving systems – and sets the markets they are used in alongside them.
The physical fundamentals, the measurands, the sources and the rulebook are covered under UV knowledge.
UV as a tool
Radiation as a production step and as a test quantity: curing, printing, cleaning, ageing tests.
Testing & qualification
Here radiation is the test quantity, not the tool – from fluorescent penetrant testing through transmission measurement and light metrology to qualification in a regulated environment.
Robotics & Automation
Once the UV source or the measuring equipment moves, the dose is no longer a single reading but an integral along a path with varying distance and angle of incidence.
Markets & Applications
The same measurand under different constraints: how UV is used and verified in industry and manufacturing, life sciences, and environment and energy.
