The National Institute of Standards and Technology (NIST) has upgraded its Synchrotron Ultraviolet Radiation Facility (SURF III), which will serve as the “nation’s standard light bulb” for optical calibrations. The facility, weighing over 180 tons, emits exceptionally pure light across the infrared, visible, ultraviolet, and X-ray regions of the electromagnetic spectrum. SURF III’s improved magnetic field uniformity and strength allow for more accurate irradiance measurements, benefiting industries like semiconductors, satellites, and medical lasers. The facility’s 13 beamlines cater to various applications, including satellite instrument calibration, semiconductor mirror characterization, and optical detector response measurement.
