چکیده
National Bureau of Standards Gaithersburg, MD 20899 A description is given of the NBS program in which special photodiodes for the far ultraviolet spectral region (5254 nm) are made available as transfer standards. These detectors are calibrated in terms of quantum efficiency (photoelectrons per incident photon) as a function of wavelength. Descriptions are also given of the calibration principles, calibration systems, and photodiode types involved in this program. Calibrations reference to the photoionization of rare gases.

Ultraviolet radiometry with synchrotron radiation and cryogenic radiometry.
The combination of a cryogenic radiometer and synchrotron radiation enables detector scale realization in spectral regions that are otherwise difficult to access. Cryogenic radiometry is the most accurate primary detector-based standard available to date, and synchrotron radiation gives a unique broadband and continuous spectrum that extends from x ray to far IR. We describe a new cryogenic rad...

متن کاملBilateral NIST-PTB Comparison of Spectral Responsivity in the VUV
To compare the calibration capabilities for the spectral responsivity in the vacuum-ultraviolet spectral region between 135 nm and 250 nm, PTB and NIST agreed on a bilateral comparison. Calibrations of semiconductor photodiodes as transfer detectors were performed using monochromatized synchrotron radiation and cryogenic electrical substitution radiometers as primary detector standards. Great i...
متن کاملRealization of the National Institute of Standards and Technology detector-based spectral irradiance scale.
A detector-based spectral irradiance scale has been realized at the National Institute of Standards and Technology (NIST). Unlike the previous NIST spectral irradiance scales, the new scale is generated with filter radiometers calibrated for absolute spectral power responsivity traceable to the NIST high-accuracy cryogenic radiometer instead of with the gold freezing-point blackbody. The calibr...
متن کاملPhotodiode array ultraviolet spectrophotometric profiling of carboxylic acids in physiological fluids.
In this paper the use of a computer-controlled photodiode array spectrophotometric detector for the high-performance liquid chromatographic (HPLC) profiling of carboxylic acids in physiological fluids is reported. The ultraviolet spectrum of the flowing eluent is obtained at 6-sec intervals and is displayed as the absorbance at 190 nm. A three-dimensional (time versus wavelength versus absorban...
