X-ray spectroscope
Abstract
Abstract An X-ray spectroscope comprising a soller slit consisting of a number of parallel plates and disposed such that one end thereof faces an X-ray emitting portion of a sample to be analyzed and a plurality of analysing crystals or total reflection mirrors disposed parallel to one another and spaced apart from one another at a suitable interval. The analysing crystals or total reflection mirrors are orientated with their one ends directed to the other end of the soller slit and such that X-rays having passed through the soller slit are incident on them with a desired angle of incidence. Also, these analysing crystals or total reflection mirrors each have a convex back side defined by inclined surfaces respectively parallel with incident and reflected X-rays and facing the reflecting surface of the next adjacent analysing crystal or total reflection mirror. With this X-ray spectroscope it is possible to make effective use of X-rays and prevent divergence in directions normal to the diffracting surface, thus permitting analysis with high efficiency.
