Compound Refractive Lens for X-Ray Focusing


Refraction of x-rays by a single lens is usually small, but a compound lens (consisting of tens or hundreds of individual cylindrical lenses arranged in a linear array) can gradually focus x-rays one- or two-dimensionally. The focal length can be controlled by the number of the lenses, i.e., the more lenses are used, the shorter focal length is achieved. Following the paper of Snigirev et al. [Applied optics, 1998, 37(4): 653-662], this use case demonstrates 1D and 2D x-ray focusing by a compound refractive lens in VirtualLab Fusion.
