P7 - Background-Corrected Determination of Optical Properties in the Far Infrared Range up to 1 mm

M. Kehrt & C. Monte
The optical properties transmittance and reflectance of materials are defined as the flux of radiation reflected from or transmitted through a sample with respect to the incident flux. Usual measurement approaches for these quantities follow these definitions and determine the quotient of the reflected or transmitted flux with respect to the incident flux. However, in the Mid and Far Infrared Range (MIR and FIR) this approach might easily lead to wrong results because background radiation...
