Claim Text:
1. An X-ray analysis apparatus comprising: an X-ray source from which an X-ray beam is emitted; at least one X-ray aperture which delimits said X-ray beam emitted by said X-ray source, said at least one X-ray aperture having a single crystal aperture body with a through pinhole, wherein said single crystal aperture body consists of one single piece of monocrystalline material, said single crystal aperture body forming a continuous circumferential edge which delimits said X-ray beam and starting from which said pinhole widens like a funnel in a direction of an outlet opening of said X-ray aperture in a first area thereof, wherein, at least in an area of said edge, a roughness depth of said X-ray aperture in one wavelength range between 10 nm and 1 μm is smaller than 100 nm; a sample position onto which the X-ray beam, which is delimited by said at least one X-ray aperture, is directed, wherein said at least one X-ray aperture, is disposed at a separation from said sample position; and an X-ray detector for detecting X-ray radiation emanating from said sample position.
