NIST Spectroradiometry Short Course

NIST is closely monitoring guidance from Federal, State, and local health authorities on the outbreak of COVID-19. To protect the health and safety of NIST employees and the American public they continue to serve, NIST has decided to postpone the event.

Spectroradiometry Short Course logo

The NIST Spectroradiometry Short Course is offered every 2 years and covers radiometry fundamentals, radiometric properties of sources and detectors, spectroradiometric techniques, reflectance properties of materials, the handling and determination of measurement uncertainties, an overview of calibration services, and the implementation of the quality system at NIST. Participants will gain experience in spectroradiometric measurement and calibration techniques using lamps, integrating spheres, spectrometers, and filter radiometers.

Dates TBD
NIST Gaithersburg, Maryland

The NIST Spectroradiometry Short Course is a 4-day course held at NIST Gaithersburg, Maryland. The course consists of lectures given by NIST scientists and hands-on laboratory experience measuring spectral radiance and spectral irradiance sources using spectroradiometers. Participants will also receive advice and assistance on spectroradiometric measurement and calibration issues, including traceability, NIST measurement equations, and measurement calibrations.

Attendance for the course is limited to 18 participants. Pre-registration is required and acceptance is determined on a first-come, first-served basis.

Who Should Attend:

This course is intended for scientists, engineers, and technicians engaged in radiometric measurements and existing or potential NIST customers relying on traceability to NIST of their sources and detectors. Existing and potential NIST customers relying on traceability to NIST using sources or detectors are encouraged to attend. Participants are expected to have some basic knowledge and experience in radiometric measurements as well as calculus. The course is suited for those who want to learn spectroradiometry systematically in depth, in theory, and in experimental practice.
