UV, IR, and SWIR Machine Vision Lights
Use UV, IR, or SWIR lighting when visible wavelengths do not produce enough contrast. The correct choice depends on how the material absorbs, transmits, reflects, or fluoresces at the target wavelength, so sample testing is strongly recommended.
Best fit
- UV fluorescence and contamination checks
- IR contrast on inks, plastics, and coatings
- SWIR inspection of selected semiconductor and packaging materials
- Material differentiation
Likely to fail when
- The camera sensor is not sensitive at the wavelength
- Optics or windows block the wavelength
- The material response is not verified on real samples
Selection inputs
- Target wavelength
- Camera spectral response
- Lens/filter transmission
- Power and heat
- Safety and enclosure requirements
