Comparison of SWIR and Visible Imaging Systems

Application Notes | Articles | EO Tech Tools | FAQs | Glossary | Marketing Literature | Newsletter | Video Resources


SWIR, or Short-Wave Infrared, light is invisible to the human eye, but detectable by specialized IR imaging lenses and cameras. The SWIR spectrum is an ideal choice for a variety of applications, including solar cell inspection, security, and bio-imaging. Ra'ef Mikhail, Optical Engineer, demonstrates the benefits of a SWIR imaging system compared to a traditional visible system by recreating a popular scene from Star Wars®. The example clearly demonstrates that the SWIR system can discern the two characters in a foggy environment, whereas the visible system cannot detect them at all. To learn more about SWIR, read our What is SWIR? application note.
