Optical Properties of Materials: A Sampling of NIST Contributions

January 1, 2000
Author(s)
Thomas A. Germer, R Gupta, Leonard M. Hanssen, Eric L. Shirley
Optics has found an extremely wide range of applications in industry and science, and the properties of the materials that make up optical instruments are key to their performance. Examples include glass for optical instrumentation such as telescopes and

Multidetector Hemispherical Polarized Optical Scattering Instrument

July 1, 1999
Author(s)
Thomas A. Germer
A multidetector optical scattering instrument is described and characterized. The instrument has twenty-eight detectors surrounding and substantially covering the scattering hemisphere. Each detector contains a polarizer so that each is only sensitive to p

Polarization of Light Scattered by Particles on Silicon Wafers

January 1, 1999
Author(s)
Li Piin Sung, George W. Mulholland, Thomas Germer
Bidirectional ellipsometry has been developed as a technique for distinguishing among various scattering features near surfaces.Employi Employing incident light with fixed polarization, the technique measures the principal angle of polarization and the

Display Reflectance Model Based on the BRDF

June 1, 1998
Author(s)
Edward F. Kelley, George R. Jones Jr., Thomas Germer
Many flat panel displays (FPDs) permit anti-reflection surface treatments that differ in character from those of traditional cathode-ray-tube displays. Specular reflection models (mirror-like, producing a distinct image) combined with diffuse (Lambertian)
