Impregnated with the oxide of a rare earth element that displays sharp absorption spikes at specific wavelengths.
These Spectralon® wavelength calibration standards are the best choice for performing calibrations of reflectometers, spectrophotometers and other spectral instruments.
Calibration data for peak absorbance wavelengths relative to maximum absorbance across the UV-VIS-NIR is provided with each calibrated standard.
The wavelength calibration standards are available in 1.25 and 2 inch diameters with an impregnation of holmium oxide, dysprosium oxide, erbium oxide or a combination of the three oxides.
