Laue lens prototypes, coloured scanning electron micrograph (SEM). These drop-like domes were carved using reactive ion etching, which produced the striped bubbles shown here. Each dark line signified a marker layer built into these ultra-precise lenses. This flawed prototype (the final lenses actually look much more like symmetrical towers) helped scientists perfect the synthesis process and prepare better lenses. The finished lenses will be used to focus X-rays to within a single nanometre using instruments like the National Synchrotron Light Source II at Brookhaven National Laboratory, New York, USA.
