The BMT-20 is a binoculars-type iris biometrics imaging device that simultaneously and quickly captures highest quality iris biometric images. Easy to use, the system can be reliably positioned by the subject with minimal instructions, or by an operator with the aid of positioning feedback LEDs on the top of the imager s housing. Product Description The patent-pending optical design of the BMT-20 features expanded depth of field and a very large tolerance for interpupillary distance, which provide superior tolerance for the positioning of all subjects eyes. The BMT-20 is ideal for enrollment programs of all sizes, including those involving very young children.
Designed with the latest in optical and system control technology by one of the leaders in the industry, the BMT-20 is physically robust, highly reliable and durable.
