Quad-RO Indirect Detection
The Princeton Instruments Quad-RO: 4320 is a fully integrated, low noise, 4-port readout camera designed for indirect imaging of x-rays using phosphor screens. This unique camera design, utilizing Princeton Instruments’ state-of-the-art cooling technology, ultra-low noise electronics and a unique fiber-optic design, offers outstanding flexibility for optimizing system performance across a wide range of X-ray energies. The compact design with the industry standard
Firewire (IEEE 1394a) interface makes the Quad-RO: 4320 perfect for OEM applications, while software selectable dual speed operations, at 500 kHz or 1 MHz, allow users to optimize camera performance for demanding applications.
