Absolute source-based radiometry is founded in the traceability of a light source’s output to measurable operational parameters. The absolute irradiance at BL-2
The extended range monochromator is based on a unique design that allows illumination of the gratings in both grazing and normal incidence, thus covering the
Detector calibrations are a crucial component of the United States industry's extreme ultraviolet (EUV) calibrations needs. Both EUV source manufacturers and
The NIST/DARPA EUV Reflectometry facility began in the late 1980's to make measurements of the reflectivity of EUV multilayer optics for lithography. Since then
The continuous-wave terahertz spectrometer makes use of two near-infrared lasers. The first laser is a fixed-frequency cw ring Ti:Saph laser operating near 840
Positron annihilation lifetime spectroscopy uses positrons to probe material defects/voids/free volume at the sub-nm scale. The general working principle is
The Synchrotron Ultraviolet Radiation Facility SURF III is operated by the Optical Radiation Group as a stable light source for radiometry and research. SURF
The Parallel Beam Diffractometer laboratory is a highly-controlled space (0.01 degree C stability) containing a set of absolutely calibrated stacked goniometer
The newly renovated solid-state NMR facility at the NIST Material Measurement Laboratory houses two spectrometers, 300 MHz and 100 MHz, primarily used for
Dual electro-optic frequency comb (DOFC) methods are being developed to enhance detection sensitivity and speed for (bio)molecular sensing in THz region. Phase
Dual electro-optic frequency comb (DOFC) methods are being developed to enhance detection sensitivity and speed for gas sensing in ultraviolet (UV) region. The
