OVERVIEW
Duplex - Double Wire Penemeter consists of Tungsten and Platinum wire pairs embedded in plastic material. Wire pairs are ordered from coarse to fine diameter. Platinum and Tungsten wires are spaced apart to correspond to the diameter of the wire in the respective wire pair. The sharpness of the image is defined by the smallest diameter wire pair that cannot be seen visually.
Duplex Penetrameters is used in EN 13068 (Radioscopy), EN 14784 and ISO 13671 (CR - Computed Radiography with Digital Films), ISO 17636-2 (Digital Radiography of Sources - Flat Panel Detectors), and ASTM E2597 (Characterization of Digital Detectors).
In addition, a new ISO standard is being prepared that describes the possibility of using Duplex IQI for determining the focal spot size of X-ray generators.
