The D1H's diode face is perpendicular to the beam when flat, for use inside traditional solid phantoms.
Exradin® D1H Diode Detector part of complete solution for: Annual QA
The Exradin® Advantage
Higher signal, flatter profiles and sharper resolution with a smaller active measurement. Precise measurement of minute fields with high visibility of the penumbra.
Minimize Angular Dependence
Exradin diodes have less than 0.5% angular dependence when tilted up to 20°, providing more confidence when measuring the penumbra or edge of the beam.
Specialized for Small Fields
The D1V's diode face is perpendicular to the beam when upright, making it ideal for photon scanning applications and use in water phantoms and the Lucy 3D QA Phantom. The D1H's diode face is perpendicular to the beam when flat, for use inside traditional solid phantoms. Both diodes provide superior measurement of field sizes up to 20 x 20 cm2 with excellent spatial resolution and minimal noise.
