Visible Spectrum Calibration Set (UV Standard)

Set of reference materials to verify the ordinate and abscissa (wavelength) accuracy of UV/Vis and UV/Vis/NIR Spectrometers. The set comprises four glass filters mounted in precision aluminum spring mounts. They are designed for use with the standard 10 mm cuvette holders of most UV/Vis and UV/Vis/NIR Spectrometers. The set is provided in a robust aluminum container. There are three neutral density glass filters for checking the ordinate accuracy and a holmium oxide glass filter for checking the wavelength accuracy of a spectrometer. Each filter has an identification number. The ordinate and abscissa values of each filter are quoted in the accompanying Certificate of Calibration. NG nominal 10%, 20%, 50%/holmium oxide filter. PerkinElmer UV Reference Materials Laboratory is ISO/IEC 17025:2005 Accredited
