HunterLab Introduces New Spectrophotometer
Reston, Va.-based Hunter Associates
Laboratory Inc. (HunterLab) now offers the UltraScan® VIS spectrophotometer designed to measure the
full range of human color perception while meeting International Commission on Illumination (CIE)
and ASTM International guidelines for accurate color measurement. Tristimulus color calculations
are performed between 360 and 780 nanometers (nm), as is recommended by the CIE, and spectral data
are reported every 10 nm. The UltraScan VIS features automated specular component
inclusion/exclusion and uses diffuse/8° geometry for measurement.
The spectrophotometer measures both transmitted and reflected color using its D65
illumination source, which is calibrated and controlled in the ultraviolet region to accurately
measure whitening agents.
Color sorting and sequencing of data measured by the spectrophotometer are simplified with
EasyGroup software. EasyMatch® QC software is available for research and quality control
