  • Description

    The Autoscan 60 is a stand-alone Reader for track etch detectors. A loaded carousel is placed in the Reader where it is driven by the motor.
    The positions containing detectors may be keyed in beforehand to save processing time. After a detector has been automatically driven to
    the read station it is edge-illuminated via a light guide. Light scattered from the tracks produces intense spots which are imaged by a
    motorised microscope and scanned by a CCTV camera. The scanned image is stored and analyzed and the identity code and track count
    retained in memory. Results are available on disc or hard copy for use by external record keeping systems.
