SWIR or Short Wave InfraRed
The SWIR is the spectral band typically defined beetwen 1 and 2.5 μm. On the boundary between visible and thermal imaging, this light field has unique properties.
Indeed, its proximity to the visible range gives it all its imaging qualities in terms of contrast and resolution, and at the same time its infrared spectrum allows it to reveal phenomena and elements invisible to the naked eye:
- See through opaque materials (plastics, silicon ..)
- Reveal elements like water, lipids, collagen ...
- See through smoke, fog and dust, day and night.
Using a powerful, controled and camera-adapted light flux, SWIRIS leads the way to new applications, overcoming the current limits of lighting.
Applications
In Machine Vision & Automation as in Scientific Imaging, applications are numerous.
