    Intelligent Recognition System Face Recognition Near-IR 940nm Bandpass Biometric Filter

     

    NIR image sensors used in conjunction with 940nm illumination are being used to support iris recognition in biometrics. When used as a secondary scanner (simultaneously with a primary, mobile scanning unit), the invisible 940nm band can similarly help improve finger-vein identification protocols. This technology identifies specific individuals using a distinct blood vessel pattern inside one’s hand. Use of a narrow band Bi940 filter can provide insurance in the event of unanticipated changes in ambient/background light.
