CALIBRATION OF SPECTRORADIOMETERS USING TUNABLE LASERS

April 22, 2021
Author(s)
Yuqin Zong, Ping-Shine Shaw, Joseph Rice, C Cameron Miller
To shorten the long calibration chain when using the conventional source-based approach and therefore to reduce spectroradiometer's calibration uncertainty, we developed a detector-based approach to calibrate spectroradiometers directly against a transfer

Recent research and development in photometry at NIST

April 22, 2021
Author(s)
Yuqin Zong, Maria Nadal, Benjamin K. Tsai, C Cameron Miller
Many developments were made in recent years in photometry at NIST for reducing measurement uncertainties, increasing calibration efficiencies, and adding measurement capabilities. The 40 years old photometry laboratory has been renovated. The new

STANDARD LEDS WITH SUPERIOR LONG-TERM STABILITY

April 22, 2021
Author(s)
Yuqin Zong, Weiqiang Zhao, C Cameron Miller
A large-chip standard LED with superior long-term stability have been developed at NIST. The standard LED uses a large, specialty die rated for 50 W but is operated under 3 W to eliminate aging effect. The standard LED was seasoned for one year and

Effect of Teflon(R) Transmittance on Sensitivity of Thermoluminescence Dosimeter Cards

May 20, 2020
Author(s)
Vyacheslav B. Podobedov, Carl C. Miller, Alexander Romanyukha, Andrew Hoy
Thermoluminescence dosimeter cards purchased by the United States Navy in recent years have different radiation sensitivities, e.g. they exhibit a different amount of light per dose unit. Presented tests indicate that the optical transparency of the Teflon

INNOVATIVE APPROACH TO COMBAT HEALTHCARE-ASSOCIATED INFECTIONS USING STANDARDS DEVELOPED THROUGH INDUSTRY AND U.S. FEDERAL COLLABORATION

February 14, 2019
Author(s)
C Cameron Miller, Timothy Rasinski
NIST Handbook 150-1, NVLAP Energy Efficient Lighting Products, presents the technical requirements and guidance for the accreditation of laboratories under the NVLAP Energy Efficient Lighting Products LAP. The 2018 revision aligns this handbook with the

Gain Calibration of Current-to-Voltage Converters

November 19, 2018
Author(s)
Thomas C. Larason, Carl C. Miller
Current-to-voltage converters are used in many photometric and radiometric applications. The calibration of current- to-voltage converters at a few input currents is not always sufficient to understand the linearity and the bias of a device. Many devices

Innovative Approaches to Combat Healthcare-Associated Infections Using Efficacy Standards Developed Through Industry and Federal Collaboration

October 5, 2018
