Instructor: David R Wyble, Avian Rochester, LLC
Level: Introductory
Benefits This course enables the attendee 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.
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.
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 is very helpful.
