Abstract

The ability to measure high reflectance coatings accurately in the visible and near infrared portions of the spectrum is essential in the production of modern building components, lighting components and solar energy conversion systems. This paper describes two computer controlled spectral reflectance measurement syste s which, with different optical inputs, share the ability to measure actual coated parts rather than relying on witness samples from a coating run. Details of the instrumentation, calibration standards, calibration and measurement process and typical results will be given.
