Abstract
An apparatus comprising an illumination source and an imaging sensor is provided to measure an iris for biometric identification purposes. The illumination source is configured to illuminate an eye to produce reflected light. The imaging sensor is configured to receive the reflected light. An optical path is formed for the reflected light from the eye to the imaging sensor.
