NIST developed the BMDO transfer radiometer (BXR) to calibrate small-aperture blackbodies for the test facilities of the Missile Defense Agency (MDA). In
A custom instrument, the Complete Hemispherical infrared Laser-based Reflectometer (CHILR), employs a gold integrating sphere and is used for the measurement of
The Fourier transform infrared spectrophotometry (FTIS) facility serves as the measurement facility for characterizing the optical properties of materials in
An integrating-sphere system has been designed and constructed for the measurement of multiple optical properties in the infrared spectral range. The absolute
The Low background infrared (LBIR) facility was originally designed to calibrate user supplied blackbody sources and to characterize low-background IR detectors
Design of the lunar irradiance instrument is based on commercially available spectrographs. These spectrographs can be stable and sub-components are readily
The Missile Defense transfer Radiometer (MDXR) is a cryogenic transfer radiometer for providing calibrations of collimated infrared beams in users' cryo-vacuum
Summary The Normal incidence Diffuse Optical Scatter Instrument (NDOSI) is a new facility for measuring the hemispherical reflectance and transmittance of
The basic SIRCUS calibration setup is shown at the right. The output from a tunable laser is sent through an intensity stabilizer, then through a 'speckle
This facility enables the measurement of spectral emittance using the direct method of radiance comparison of the sample with a blackbody reference source
The Telescope Calibration Facility (TCF) was designed to support the NIST Stars project by providing a facility to radiometricly calibrate long focal length
The NIST Thermal-infrared Transfer Radiometer (TXR) is used for measuring the radiance temperature in the thermal-infrared spectral region of extended-area
