11. Standardization of Broadband UV Measurements for 365 nm LED Sources
Series: Journal of Research (NIST JRES)
Report Number: 117.004
Published: 2/2/2012
Author: George P Eppeldauer
Abstract: Broadband UV measurements are analyzed when UV-A irradiance meters measure optical radiation from 365-nm sources. The CIE standardized rectangular-shape UV-A function can be realized only with large spectral mismatch errors. The spectral power-di ...

12. Comparison of a detector-based near-IR radiance-scale to an ITS-90 calibrated radiation thermometer
Published: 8/7/2011
Authors: George P Eppeldauer, Howard W Yoon, Jinan Zeng, Thomas C Larason
Abstract: Integrating-sphere-input InGaAs radiometers have been developed at the National Institute of Standards and Technology (NIST) to extend the detector-based calibrations from the Si range to the near-IR. These near-IR radiometers are used to determine t ...

13. Increased responsivity pyroelectric radiometer with dome input and temperature control
Published: 7/18/2011
Authors: George P Eppeldauer, Jinan Zeng, Leonard M Hanssen
Abstract: Pyroelectric radiometers with noise-equivalent-power (NEP) close to 1 nW/Hz¿ have been developed to measure less than 1 microwatt radiant power levels at room temperature to 25 micrometer. The radiometers will be used as transfer standards for routin ...

14. Calibrations of Current-to-Voltage Transimpedance Amplifiers Using Electrical Standards
Published: 6/13/2010
Authors: Howard W Yoon, George P Eppeldauer, Dean G Jarrett, Thomas C Larason, Wan-Seop Kim
Abstract: For photocurrent measurements with low uncertainties, a wide-dynamic range current-to-voltage converter traceable to resistance standards has been developed at the NIST. The design and calibration of the converter standard are described. For validat ...

15. Spectral irradiance responsivity calibration of InSb radiometers using the improved IR-SIRCUS at NIST
Published: 10/15/2009
Authors: Jinan Zeng, Howard W Yoon, George P Eppeldauer, Leonard M Hanssen, Joseph Paul Rice
Abstract: The spectral irradiance responsivity calibrations of InSb radiometers measured on the tunable-laser based Infrared Spectral Irradiance and Radiance Responsivity Calibration with Uniform Sources (IR-SIRCUS) facility are discussed. This work describes ...

16. The Extension of the NIST BRDF Scale from 1100 nm to 2500 nm
Published: 8/21/2009
Authors: Howard W Yoon, David W Allen, George P Eppeldauer, Benjamin K Tsai
Abstract: Measurements of bi-directional reflectance factor for diffuse reflectance from 1100 nm to 2500 nm using extended-range indium gallium arsenide (exInGaAs) detectors in the NIST Spectral Tri-function Automated Reference Reflectometer (STARR) facility ...

17. Extension of the NIST spectral responsivity scale to the infrared using improved-NEP pyroelectric detectors
Published: 6/2/2009
Authors: George P Eppeldauer, Jinan Zeng, Howard W Yoon, Boris Wilthan, Thomas C Larason, Leonard M Hanssen
Abstract: Routine NIST spectral responsivity calibrations are needed for the infrared range. Low NEP pyroelectric radiometers have been developed for traditional monochromator applications to extend the responsivity scale to the infrared. After NEP tests, the ...

18. Radiometer standard for absolute responsivity calibrations from 950 nm to 1650 nm with 0.05% (k = 2) uncertainty
Published: 6/2/2009
Authors: George P Eppeldauer, Howard W Yoon, Yuqin Zong, Thomas C Larason, Allan W. Smith, M. Racz
Abstract: A sphere-input transfer-standard detector has been developed to calibrate detectors and radiometers for absolute spectral power, irradiance, and radiance responsivity in the near-IR range with uncertainties similar to those of silicon trap-detector c ...

19. Extension of the NIST tristimulus colorimeter for solid-state light source measurements
Published: 5/29/2009
Authors: George P Eppeldauer, Carl C Miller, Thomas C Larason, Yoshihiro Ohno
Abstract: In order to obtain improved color measurement uncertainties for solid state light (SSL) sources, the second generation tristimulus colorimeter of NIST has been extended with a fifth channel to perform efficient matrix corrections for the spectral mis ...

20. Illuminance responsivity calibration of reference photometers at the NIST SIRCUS and SCF facilities
Published: 5/29/2009
Authors: George P Eppeldauer, Carl C Miller, Thomas C Larason, Yoshihiro Ohno
Abstract: The illuminance responsivities of two transfer standard photometers have been directly determined from their spectral responsivity calibrations at two different calibration facilities of NIST. The main characteristics of the two photometers, and thei ...
