Crystal Optics

Crystal-based X-ray optics are essential and critical optical components of synchrotron light sournces and XFELs. The Crystal Optics section has comprehensive in-house infrastructure, capabilities and expertise for fabricating and developing almost all kinds of crystal-based X-ray optics, including crystal monochromators, analyzers, high-heat-load monchromators, beam splitters, polarizers, mirror substrates, ultrahigh-resolution crystal optics systems, FEL crystal optics, etc., for APS beamlines as well as
Expertise includes:

Designing crystal optics with X-ray dynamical-theory calculations and modeling to achieve desired resolution, efficiency, acceptance, etc.,
Fabricating (and refurbishing) ultrahigh-quality crystal optics (Si, Ge, quartz, sapphire, diamond), from precise orienting, cutting/dicing, grinding, etching, to strain-free polishing
X-ray characterization and testing of crystal optics using X-ray topography and double-crystal rocking curve imaging.
