Abstract:

Compound refractive x-ray lenses have recently been developed by Adelphi Technology and others. These lenses allow direct imaging, just as visible light optics, which are also refractive. Such a capability opens a range of high resolution x-ray imaging applications. However, the lenses have extremely small apertures (less than 1 mm) and are relatively long (several cm) limiting collection efficiency and field of view. Furthermore, the focal length depends strongly on the x-ray wavelength. These design issues, along with results of recent imaging experiments will be discussed.
