13. Spectral Radiance Comparisons of Two Blackbodies with Temperatures Determined Using Absolute Detectors and ITS-90 Techniques
Published: 9/1/2003
Authors: Howard W Yoon, Charles E Gibson, J L Gardner
Abstract: For calibrations of spectral irradiance standards, a high-temperature blackbody (HTBB) is used as a source of spectral radiance or irradiance as derived from Planck's radiance law. The temperature of such a blackbody can be determined using radiance ...

14. The Development and Characterization of an Absolute Pyrometer Calibrated for Radiance Responsivity
Published: 9/1/2003
Authors: David W Allen, Robert D. Saunders, Bettye C Johnson, Charles E Gibson, Howard W Yoon
Abstract: The International Temperature Scale of 1990 (ITS-90), for temperatures above the freezing temperature of silver, is defined with pyrometers which rely upon spectral radiance ratios to one of the silver, gold or copper freezing temperature blackbodies ...

15. Comparison of Cryogenic Radiometry and Thermal Radiometry Calibrations at NIST Using Multichannel Filter Raidometers
Published: 2/1/2003
Authors: Bettye C Johnson, Steven W Brown, Keith R Lykke, Charles E Gibson, G Fargion, G Meister, S B. Hooker, B L Markham, James J. Butler
Abstract: Comparison of independent measurement results allows an assessment of the accuracy of the underlying methods. In this work, four multichannel filter radiometers were calibrated using tunable laser-illuminated and lamp-illuminated integrating sphere ...

16. FASCAL 2: A New NIST Facility for the Calibration of the Spectral Irradiance of Sources
Published: 2/1/2003
Authors: Howard W Yoon, J E Proctor, Charles E Gibson
Abstract: The Facility for Automated Spectroradiometric Calibrations (FASCAL) is the primary facility for spectral irradiance and spectral radiance calibrations at NIST and has been in continous use since the early 1970's. Due to the increasing demands for sp ...
