What are Polycapillary Optics?

Polycapillary Optics are sophisticated X-ray focusing devices based on the principle of total internal reflection. These systems consist of bundles of hollow glass capillaries that guide X-rays through multiple reflections, functioning as highly efficient waveguides. This unique technology allows for the transmission of X-rays in a straight line or along a precisely defined curvature, enabling unparalleled control over X-ray beams. Because these optics can collect and redirect divergent radiation, they significantly enhance signal intensity while minimizing background noise. This makes them indispensable in applications requiring precise X-ray manipulation.

The fundamental working mechanism involves X-ray photons entering the hollow capillaries at grazing incidence angles. When these angles are below the critical angle for total external reflection, the photons undergo numerous reflections along the inner walls of the capillaries, eventually exiting with minimal energy loss. This capability has transformed analytical techniques in fields ranging from materials science to medical imaging, offering a versatile solution for various X-ray analysis challenges.
