The NIST Physical Measurement Laboratory has established the color and appearance metrology facility to support calibration services for 0°/45° colored samples, 20°, 60°, and 85° specular gloss samples, research in the colorimetric characterization of gonioapparent including a new standards for metallic coatings and calibrated photographic and x-ray step tablets.
Instruments and capabilities:
|Reference 0:45 reflectometer - The primary purpose of the 0:45 reflectometer is to disseminate color standards to the color and appearance community. The instrument...|
|Goniophotometer for specular gloss calibrations - Specular gloss is the perception by an observer of the mirror-like appearance of a surface. The measurement of specular gloss consists...|
|Five-axis goniometer for BRDF measurements - Manufacturers are creating pigments with new and unique appearance attributes. For example, gonioapparent materials such as metallic and...|
|Reference transmittance densiometer (RDT) - The Reference Transmission Densitometer (RTD) is the national reference instrument for standard diffuse visual transmittance density measurements...|
