Application Note: Determining the Effects of Angle on the Infra-Red Reflectance Properties of Thin Films in Architectural Glass Using the Agilent Cary 630 FTIR
18 April 2013
The glass used in buildings plays a key role in keeping the building energy efficient. Similar to walls and ceilings being insulated, glass can be coated to alter the reflectivity of infrared (IR) light. FTIR spectroscopy can be used to measure the characteristics of the thin films across the IR spectral range. These measurements complement similar UV-Vis-NIR measurements and the ability to collect both types of data allows for a more complete characterization of the coating. This application note demonstrates how the Agilent Cary 630 FTIR can be used to compare the reflectivity of coatings on a piece of coated architectural glass.
