Spectralon pastel colors tandards are ideal for use in the laboratory
or manufacturing situations where the environment may be unpredictable,
or where tight color tolerances are required. These color pastel
standards provide highly stable, reproducible spectral reflectance.
The pastel line of color standards exhibits the same high reflectance
properties found in all Labsphere Spectralon products: lambertian
behavior, stability and durability.
The
reflectance of the color pastel standards is extremely consistent
and very reproducible. The standards are designed to aid in developing
consistent color reproduction for manufacturers of paper and textiles,
where colors are frequently less saturated than those used in
plastic or metals. Consistent reflectance is critical for quality
control in the manufacturing process. Spectralon pastel color
standards are non-thermochromic, this means that their color is
consistent and not affected by temperature shifts in the manufacturing
or laboratory environment. Research has shown that a 10°C shift
in temperature of the manufacturing or laboratory site causes
most commercially available color standards to exhibit some thermochromism1.
Because of the thermally stable properties of these color
pastel standards, there is no need to control temperature in a
laboratory setting. This attribute makes the standards especially
well suited to sites where temperature swings may exceed 10° C.
All
standards a spectrophotometrically calibrated in our state-of-the-art
Reflectance Research laboratory with standards traceable to national
laboratories. Calibration is available in 0°/45° hemispherical
geometry or 8°/hemispherical geometry. Data is available for illuminants
A, C, and D65 for both CIE 1931 observer and CIE 1964 10° observer.
