Color and appearance

Ongoing
We are developing instrumentation, standards artifacts, and measurement protocols to characterize appearance attributes including color, texture, and gloss

NIST Ballistics Toolmark Database

Ongoing
The NIST Ballistics Toolmark Research Database is an open-access research database of bullet and cartridge case toolmark data. This database will: foster the

Optical grating scatterometry

Ongoing
This program aims to develop standards, methods, and modeling for assessing the periodic structures using optical reflectance and transmittance measurements.

Optical Polarization Metrology

Ongoing
This program aims to improve the metrology of optical polarization by developing new measurement methods and theoretical understanding of polarization phenomena

Optical scattering from surfaces

Ongoing
We study how material properties, surface topography, and contaminants affect the distribution of light scattered from surfaces. Our aim is to support industry

Reflectance Measurements of Human Skin

Ongoing
The purpose of this human subjects study is to collect high-quality measurements of the reflectance spectrum of human skin and assess the variability across the

Spectral Reflectance and Transmittance

Ongoing
NIST maintains the national scales for reflectance and transmittance in the ultraviolet, visible, and near-infrared spectral regions (250 nm to 2500 nm). Our

Spectrophotometry

Ongoing
Spectrophotometry is a quantitative measurement technique that allows scientists to investigate the optical properties of materials over a wide wavelength range
