The optics module contains support for devices used to modify the x-ray beam from a synchrotron source and apply it in experimentally useful ways, including a variety of monochromators, slits, filters, mirrors, diffractometers, and optical tables.

The optics module is part of synApps.

Supported Devices

Monochromators

• Non-dispersive double-crystal with symmetric offset (Kohzu/PSL geometry 1)

• Dispersive double-crystal – nested geometry
• Dispersive double-crystal – symmetric geometry
• Spherical grating
• Multilayer

Slits

• 2-blade slits (with optional soft motor front end)
• 4-blade graphic slits
• XIA HSC slits
