Abstract
The Infrared Optical Properties of Materials program in the Sensor Science Division at the NIST continues to its efforts to expand its capabilities to meet the demand for high accuracy measurements of optical properties over a wide range of measurement types and key parameters. These efforts include expansion of the spectral coverage for several properties including reflectance, emittance, index of refraction. We will report on progress in establishing new instrumentation, including integrating spheres, a hemi-ellipsoidal collecting mirror system, Fourier transform spectrometers and infrared refractive index measurement system. Finally, we will describe a new effort in support of additive manufacturing needs, which should allow us to extend the temperature range of emittance and reflectance of certain materials up to 3000 K.
