Spectralon® Wavelength Calibration Standards
Labsphere Spectralon® Wavelength Calibration Standards are formulated by impregnating a Spectralon substrate with the oxide of a rare earth element which displays sharp absorption spikes at specific wavelengths. Complete absorption spectral data is supplied with each standard. The three standards available are Holmium Oxide for the UV-VIS-NIR calibrations, Dysprosium Oxide for NIR calibrations and Erbium Oxide – for VIS-NIR calibrations.
These durable and chemically inert standards are ideal for wavelength calibration of spectrophotometers, reflectometers and other spectral instruments.
