CRITICAL-ANGLE TRANSMISSION (CAT) GRATING

Scanning electron micrograph of the hierarchical structure of a large-area CAT grating membrane fabricated from a silicon-on-insulator wafer.

Shaping of thin-foil x-ray optics

X-ray optics for space-based applications need to be wafer-thin AND maintain accurate figure.
