Rapid,
reliable and highly reproducible results are achieved using the Minolta™ CM-2002 Photospectrometer.
This instrument covers the visible wavelength range from 400 to 700 nm,
providing a number of light source types and observer angles, and producing a
range of colour indices, including Munsell Hue, Value and Chroma, L*a*b*
indices, and reflectance data and curves. Calibration
of the instrument is carried out for every analysis to black, white and CERAM II
colour standard materials.
