About the Electron and Optical Physics Division
The Division, part of NIST's Physics Laboratory, develops measurement capabilities needed by emerging electronic and optical technologies, particularly those required for submicrometer fabrication and analysis. In pursuit of this mission, it maintains an array of research, measurement, and calibration activities.

Research Areas
The Electron and Optical Physics Division is divided into two groups:
   
- Photon Physics Group: performs research in the areas of far ultraviolet and extreme ultraviolet (EUV) physics.
   
- Far Ultraviolet Physics Group: is responsible for SURF III operations and for source-based radiometry and calibration services in the far UV and soft x-ray spectral regions.

Panoramic view from the west of the machine hall of the SURF III Synchrotron Ultraviolet Radiation Facility
Panoramic view from the west of the machine hall of the SURF III Synchrotron Ultraviolet Radiation Facility, located in the basement of the NIST Radiation Physics Building. The blue-topped cube in the center rear of the picture is a 180-ton iron yoke of an electromagnet, whose current coils are the yellow cylinders visible in its center. Between those coils sits a hollow stainless steel ring, of 84 cm central radius, within which circulates an ultrarelativistic electron beam. The light produced by that beam is fed into beamlines that tap into tangent points of the ring. Five such beamlines are visible here - the aluminum foil-wrapped tubes that extend outward from the ring; another seven are located behind the main magnet cube, some of which extend into an adjacent laboratory module. SURF III is the U.S. national primary standard for source-based optical radiometry from the infrared through extreme ultraviolet spectral regions. It also serves an international user community in climate change, ultraviolet astronomy, lighting, nanomanufacturing, plasma physics and extreme ultraviolet optics applications.
