Set of reference materials to verify the ordinate and abscissa/wavelength accuracy of UV/Vis and UV/Vis/NIR Spectrometers.

• Provided mounted in aluminum spring mounts
• Delivered in a robust aluminum container
• Individually numbered filters
• Accompanying Certificates of Calibration

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.
