X-ray XDI
High Resolution X-ray camera
The X-ray XDI is a high resolution (1392 x 1040 pixels), X-ray digital camera with direct coupled (micro) fiber-optic input that protects the sensor against radiation damage.
The camera offers a switchable 10/20MHz readout rate (with 12-bit image digitization) to cope with real time acquisition requirements such as for PCB inspection, X-ray source monitoring.
Simultaneous exposure and read out cycle allows 100% duty cycle to be achieved whilst maintaining sensitivity.
Resolution up to 25lp/mm is achieved depending on the input size and scintillator thickness options chosen at the time of order.
Very low read out noise electronics down to 5 electrons allows the X-ray XDI to detect very faint flux close to near photon counting when binning is used.
This is particularly useful for low dose micro-CT as well as SAXS set up. Thanks to large dynamic range, the camera can unveil very faint intensity details even a bright background with no saturation artifacts.
