Abstract
A commonly used metric for measuring the reflective properties of a sample is Directional Hemispherical Reflectance (DHR). The Infrared Grazing Angle Reflectometer measures DHR at high angles of incidence. To facilitate this measurement, a novel three dimensional multi-face pyroelectric detector is used. This detector can theoretically measure better than 98% of the light reflected by the sample, regardless of the diffusivity of the sample measured. The setup of this equipment is discussed, and the procedure for calibration is derived. Several of the difficulties in performing measurements are described, and several sample measurements are discussed.
