Spectralon
high-reflectance gray scale standards are used to establish the
linearity and accuracy of reflectance spectrophotometers and colorimeters.
The standards are suitable for users who need a wide dynamic range
of reflectance values that are abbreviated in range, but not in
number of calibration steps. Industries such as clay and processed
minerals, paper, and paints typically require such a range, which
accurately reproduces the range of reflectance values exhibited
by those products.
The
standards are offered as a set of eight, with a range of reflectance
values from 80% to 94%, in 2% reflectance factor steps. They are
supplied with calibration data traceable to national laboratory
standards in geometries of 8°/hemispherical (specular included
or excluded) or 0°/45° geometries. Each standard is housed in
a durable delrin holder with a protective cover.
Spectralon
gray scale reflectance standards are highly lambertian over their
effective spectral range (350 to 830 nm). The standards offer
the consistent reflectance, thermal stability, and durability
associated with all Labsphere Spectralon products.
