16 bit CCD

16 bit CCD camera: Photonic Science water cooled X-Ray Hystar 2048

The camera head comprises a very high resolution 2048 horizontal x 2048 vertical pixels, full frame CCD imager, which is directly bonded to a tapered fibre optic which has an input diameter of 28mm OD.
A GadOx scintillator has been deposited directly onto the front surface of this tapered fibre-optic. The scintillator thickness is optimized for X-ray energies in the range 20 to 80 keV (equivalent to a density of 30 mg/cm2).

Three optic systems are available for this CCD camera corresponding to the following parameters:

1) 3.8 µm pixel size, Gadox screen thickness ca. 10 µm (PSF of the order of 13 µm);

2) 14 µm pixel size, Gadox screen thickness ca. 20 µm (PSF of the order of 35 µm);

3) 14 µm pixel size, Gadox screen thickness ca. 40 µm (PSF of the order of 60 µm).
