Company Brief

Incoatec was founded in 2002 by scientists as a spin-off of the GKSS Research Center in Geesthacht near Hamburg (today Helmholtz Center hereon GmbH) together with Bruker AXS in Karlsruhe, one of the leading manufacturers of X-ray Analytic Systems worldwide. Incoatec develops, produces and supplies components for X-ray analytical systems. These components include optics, mirrors, and microfocus sources for applications in x-ray diffraction, x-ray scattering, and x-ray spectrometry. Incoatec offer solutions for chemistry, pharmacy, semiconductor industry, heavy industry, life science and nanotechnology, enabling our customers to make better use of their resources and improve their results. Using extensive know-how in thin film technology together with in-house mechanical and electronic workshops, Incoatec are able to provide reliable, efficient and environment-friendly products: Made in Germany.


SCATEX - Incoatec´s scatterless pinholes

Parasitic scattering caused by apertures is a well-known problem in X-ray analytics, which forces users and manufacturers to adapt their experimental setups to this unwanted phenomenon. Increased measurement times due to lower photon fluxes, a lower resolution caused by an enlarged beam stop, a larger beam defining pinhole-to-sample distance due to the integration of a scatter guard and generally a lower signal-to-noise ratio lead to a loss in data quality.

A reduction of parasitic aperture scattering is possible with scatterless slits. However, since the noise signal is generally still too high, synchrotron facilities, for example, are required to further use antiscatter guards. Furthermore, (scatterless) slit systems suffer from the rectangular beam shaping which increases the beam stop size by at least 41.4% (corresponds to √2) compared to a circular beam shaping pinhole. Thus, beam definition with pinholes is advantageous as it enables a considerably higher resolution.

The new SCATEX pinholes produce almost no parasitic scattering and overcome the aforementioned problems.
