Reflectance Wavelength Calibration Standards
Rare Earth Oxide Standards are for the calibration of UV-Vis-NIR spectrometers
and spectrophotometers. These wavelength calibration standards
display sharp absorbance peaks over much of the UV-Vis-NIR
spectral range. The mixture of rare earth oxides are chosen to give the
best coverage over the wavelength range of interest. UV-Vis and Vis-NIR
standards are available both in regular sizes and in custom sizes
UV-Vis Calibration Standards are a mixture of holmium and erbium
oxides in an inert, durable, spectrally neutral matrix. The UV-Vis standards
are traceable to the National Research Council Canada and NIST.
Available in 1.25" (37 mm) and 2" (50.8 mm) diameter sizes in a Delrin™
holder with cover. These standards are ideal for calibration of
UV-Vis spectrophotometers. They are calibrated from 250-850 nm.
Near Infrared Calibration Standards are a mixture of dysprosium,
holmium, and samarium oxides in an inert, durable, spectrally neutral
matrix. These Avian Technologies wavelength calibration standards are
traceable to the National Research Council Canada and NIST. They are
available in 1.25" (37 mm) and 2" (50.8") diameter sizes in a DelrinTM holder with cover.
In addition to these standards, there are similar highly purified powder
standards in hermetically sealed 1.5 inch (37 mm) dia anodized aluminum
holders with optical glass windows in accord with NIST SRM-1920a.
