Labsphere’s Spectralon® wavelength calibration standard sets consist of three calibration standards covering the UV-VIS-NIR region of the spectrum. Each standard is 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. Custom wavelength calibration standards are also available to meet your individual needs.
