Precisely fitting and highly effective optics for your applications.

The mode of operation of X-ray capillary optics is based on the effect of the total external reflection of X-rays on the inner, very smooth surfaces of the glass capillaries. For very small angles of incidence, almost 100 % of the X-rays are reflected by the glass wall of the capillary and can therefore be guided through the optics with extremely low losses. X-rays can thus be shaped and concentrated through targeted deformation of the capillaries.

Imaging optics

The combination of large polycapillary structures (d ≤ 20 mm) with a CCD sensor enables energy- and spatially-resolved imaging of a sample. This allows the element distribution of the sample to be visualized without having to ablate it. A magnification of between 1:1 and 1:10 is possible.

Optics types

  • X-ray light guide

      X-ray light guides. Efficient transmission and collimation of divergent X-rays.

      The simplest version of capillary optics is the X-ray light guide, a cylindrically shaped monocapillary. It collimates the X-ray beam spatially and limits the angle of divergence at the beam exit. Compared to a pinhole aperture, the X-ray light guide significantly increases the intensity on the sample. Depending on the application objective, X-ray light guides can be manufactured with different diameters and lengths.

      Each optic is custom-designed according to your requirements and closely coordinated with you. Please do not hesitate to contact us.
