As part of the Commerce Department's Technology Administration, the National Institute of Standards and Technology (NIST) works to strengthen the U.S. economy and improve the quality of life by working with industry to develop and apply technology, measurements, and standards. NIST carries out its mission through a portfolio of four major programs:

  • Measurement and Standards Laboratories that provide technical leadership for vital components of the nation's technology infrastructure needed by U.S. industry to continually improve its products and services
  • Advanced Technology Program, which accelerates the development of innovative technologies for broad national benefit through R&D partnerships with the private sector
  • a grassroots Manufacturing Extension Partnership with a nationwide network of local centers offering technical and business assistance to smaller manufacturers
  • a highly visible quality outreach program associated with the Malcolm Baldrige National Quality Award that recognizes continuous improvements in quality management by U.S. manufacturers, service companies, educational organizations, and health care providers.

In fiscal year 2005, NIST is operating on a budget of about $858 million with nearly 3,000 staff members at its sites in Gaithersburg, MD, and Boulder, CO, News and general information about NIST programs and services are available on the NIST homepage, or call General Inquiries at (301) 975-NIST or (301) (975-6478); or e-mail: inquiries@nist.gov.

Course Description

The need for education and training for photometry engineers in industry has been stressed by the Council for Optical Radiation Measurements (CORM), Lamp Testing Engineer's Conference (LTEC), and other metrology groups in industry. In response to this need, the Short Course on Photometry has been established by NIST. The course was successfully offered in 1998, 1999, 2000, 2001, 2002, and 2003. Due to favorable response and continuing demand, the seventh one is planned for 2005. The course, planned for three and half days with a limit of 28 participants*, is aimed mainly at customers of NIST photometric calibrations, and more widely, engineers and technicians engaged in photometric work in industry. The course will cover fundamentals in photometry and colorimetry and practical aspects of measurements of luminous flux, luminous intensity, illuminance, luminance, color temperature, and chromaticity of light sources. The course will consist of 10 lectures given mainly by NIST scientists and 3 hands-on laboratory sessions at the NIST photometry laboratory using the 4 m bench, the 2.5 m integrating sphere, and the color temperature measurement facility. Course participants, divided into three groups, will perform actual measurements of total luminous flux, luminous intensity and illuminance, and color temperature. Participants will gain experiences in the calibration of lamps, photometers, and colorimeters. This course does not cover radiometry in general, for which another NIST course provides.

* Registration for the laboratory sessions is limited to 18 persons.
Who Should Attend

This course is intended for photometry engineers and technicians in industries such as lighting, photography, and avionics; calibration and testing laboratories; instrument manufacturers; and others. Participants must have some basic knowledge and experience in photometric or radiometric measurements as well as calculus. The course is suited for those who want to learn photometry systematically in depth, in theory, and in experimental practice.
Instructors

The instructors from the NIST Optical Technology Division are Dr. Yoshi Ohno, Dr. Steve Brown, Dr. Cameron Miller, and Ms. Sally Bruce. Dr. Georg Sauter, a distinguished invited scientist from Physikalisch-Technische Bundesanstalt (PTB), Germany, will also join us to give lectures. Yoshi Ohno is a physicist and group leader of the Optical Sensor Group. He authored NIST SP250-37 Photometric Calibrations and two chapters in the OSA Handbook of Applied Photometry. Steve Brown is a physicist and is responsible for colorimetry of displays as well as absolute detector metrology. Cameron Miller is a research chemist and is the leader of the photometry project at NIST. Yuqin Zong is a research staffer and is responsible for photometric calibrations. Sally Bruce is a physical scientist working in the area of detector metrology and also serves as the division's quality manager.
Location

The course will be held at the National Institute of Standards and Technology, Metrology Building (220), Room B341, Gaithersburg, Maryland. Gaithersburg is located approximately 40 km northwest of Washington, DC.
