Beamline 7: EUV reflectometry

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

BMDO transfer radiometer (BXR)

NIST developed the BMDO transfer radiometer (BXR) to calibrate small-aperture blackbodies for the test facilities of the Missile Defense Agency (MDA). In

Continuous-wave terahertz spectrometer

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

Lunar spectro-radiometer

Design of the lunar irradiance instrument is based on commercially available spectrographs. These spectrographs can be stable and sub-components are readily

NIST Gonio-spectroradiometer

The NIST gonio-spectroradiometer is used to measure total spectral radiant flux (TSRF) of incandescent lamps. The instrument consists of a 3-axis scanning
