High-resolution X-ray Imaging
Xcam X-ray imaging technology offers unparalleled choice for your
scientific application. The information below is provided to give
a sample of what we can offer, but we can tailor any system to
your requirements. The possible options for chips scintillators,
entrance windows, to name but a few components, are too varied
to tabulate. Contact us to discuss your specific requirements.
Xcam X-ray imaging systems provide:
- High-resolution, up to 35µm FWHM for indirect detection
- Indirect or direct detection of X-rays for optimization of
the detection system response to your requirement
- Cryogen-free thermoelectric cooling, with supplementary water-cooling
- A selection of entrance windows are available for optimal transmission
at your energy range of interest
- 12, 14 or 16 bit digitisation
- <5 electrons rms noise, depending on CCD type
- Full software control of your system including, readout parameters,
binning and windowing modes

Notes:
I = Indirect detection of X-rays , using
a scintillator to shift the X-ray wavelength into the optical region,
where the CCD is more sensitive. This has the effect of extending
the QE towards hard X-ray energies. Larger imaging areas can be
provided using a magnifying fibre optic taper.
D = Direct detection of X-rays , which
results in a better sensitivity, Signal to noise ratio and spatial
resolution for lower energy X-rays
Images
Image taken of a moth's head taken in an X-ray microscopy configuration.
Fly's foot joint - dataset image (left) and longitudinal section
through reconstructed volume (right), FOV 340um (approx 1.3 um
per pixel). This image was taken by CSIRO with equipment supplied
by Xcam, and was published in the Journal of Microscopy, vol. 207,
pt. 2, August 2002, page 94, and published with Blackwell's permission. Further information about this application, using Xcam hardware for X-ray projection microscopy, can be found on the 'Application Notes' page of this website.
This image of this CCD shows its large size - 62mm x 28mm.
