Fundamentals of Spectral Measurements for Color Science
Instructor: David R. Wyble, Avian Rochester, LLC
Level: Introductory
Duration: 2 hours plus 15 minute break.  After the class, adjourn to Zoom to join the instructor and other students in a discussion of the class.
Course time:
    New York: Wednesday 11 November, 10:00-12:15
    Paris: Wednesday 11 November, 16:00-18:15
    Tokyo: Thursday 12 November, 00:00-02:15

Benefits:
Attendees will be able to:

• Identify the components of spectrophotometers and spectroradiometers and the functions of each.
• Define the standardization (calibration) process of spectrophotometers and understand the implications of standardization upon the measurement process.
• Interpret measurement requirements and select appropriate measurement parameters and geometries for various applications.
• Experience (virtual) hands-on demonstrations of instruments and software.
• Understand the point of “hand-off” from spectral measurements to colorimetric calculations.

Intended Audience: color engineers and technologists responsible for making and interpreting color measurements of any type. A technical background is not required, although an understanding of basic scientific principles will be very helpful.

Course Description:
This class begins by defining the basic terms surrounding the instruments and quantities used in spectral measurements in the color field. We then cover the operation and construction of spectrophotometers and spectroradiometers by discussing the function of each of the various subsystems present in the devices. Instrument standardization (calibration) and the application of CIE geometries for reflectance and transmittance is covered. To evaluate instruments, the concepts of precision and accuracy of measurement devices is introduced along with practical suggestions for the analysis of instrument performance. The overall goal is to fully understand the procedures and concepts that lead to proper spectral measurements that are the basis for colorimetric calculations.

David R. Wyble is president and founder of Avian Rochester, LLC. Since 2011, Avian Rochester has been delivering color standards, traditional and custom measurements, and consulting services to the color industry. Prior to founding Avian Rochester, Wyble was a color scientist within the Munsell Color Science Laboratory, at the Rochester Institute of Technology, and before that a member of research & technology staff at Xerox Corp. He holds a BS in computer science and MS and PhD in color science from RIT and Chiba University, respectively.
