Spectralon Wavelength Calibration Standards

Labsphere Spectralon Wavelength Calibration Standards

Stable absorption spectra for validating the wavelength calibration of spectrophotometers

Spectralon wavelength calibration standards provide stable absorption spectra for validating the wavelength calibration of spectrophotometers in the UV-VIS-NIR region. Each standard is formulated by doping Spectralon with a rare earth oxide that exhibits sharp absorption peaks at specific wavelengths. Complete absorption spectral data is supplied with each standard. A holmium oxide standard is available for UV-VIS-NIR calibrations, while a dysprosium oxide standard is offered for NIR calibrations. Meanwhile an erbium oxide standard is provided for VIS-NIR calibrations. Alternatively, a mixed oxide standard is available that is doped with all three rare earth oxides for use over the entire UV-VIS-NIR region.

These durable and chemically inert standards are ideal for performing a wavelength calibration on spectrophotometers, reflectometers and other spectral instruments. Calibration data for peak absorbance wavelengths and relative to maximum absorbance is provided with each standard. Calibration is traceable to the US National Institute of Standards and Technology (NIST). The individual rare earth oxide standards are available in sets of three and all standards are available in 1.25 and 2.00 inch diameters.
