The extra large headbox allows for very natural behavior even of most restless participants. 

The SMI REDn Scientific is also highly robust for vision corrections (glasses and contact lenses), as well across ethnicities and age groups, providing an extremely broad population coverage. 

Outstanding precision and accuracy provided by a new generation of eye tracking algorithms ensure reliable results. Based on two decades of experience and the best available technology, the SMI REDn Scientific is designed to ensure instant eye tracking in any environment.

Eight TTL inputs allow to reliably synchronize eye tracking data with biometric data sources, such as EEG, either directly, or via a dedicated synchronization hardware such as StimTracker for SMI.
