Extracting Infrared Absolute Reflectance from Relative Reflectance Measurements
Volume 66, Number 6 (June 2012) Page 680-684

Absolute reflectance measurements are valuable to the optics industry for development of new materials and optical coatings. Yet, absolute reflectance measurements are notoriously difficult to make. In this paper, we investigate the feasibility of extracting the absolute reflectance from a relative reflectance measurement using a reference material with known refractive index.
