SWIR close-ups of the human eye, as shown above, demonstrates the level of detail that can be reproduced. The transparency of the cornea extends well into the SWIR band enabling all the fine detail of the iris to be reproduced. This fine structure is a unique identifier of the individual and matching algorithms and databases built on data taken in the visible should be fully applicable to the SWIR images. This opens up new flexibility in capturing iris images. Most importantly, SWIR offers the ability to capture iris images at distance with controlled lighting sources that are eyesafe and essentially undetectable. SWIR offers the truly unique possibility of capturing iris images even when the individual wears regular eye glasses or even sunglasses.
