Each didymium standard is supplied with instructions on proper usage, an NSG Precision Cells Unique Lifetime Warranty and a Certificate of Calibration. NSG standards are calibrated by default for 2nm slit-widths but upon request, customers can specify any slit-width between 1.8-2.2nm. Because measured wavelength peaks depends on the user’s spectrophotometers slit-width (spectral band-pass) we offer a special calibration kit customized to the desired slit-width for an additional charge.
In summation, the advantages of NSG’s WAV-7 didymium glass standard for calibrating wavelength accuracy are legion. First, the WAV-7 calibration standard for wavelength accuracy is not only NIST-compliant but actually exceeds their requirements for tolerance. Secondly, the unique materiaI formation and nano-deposition proprietary manufacturing process assures unmatched stability of optical performance for calibrating wavelength accuracy. NSG’s WAV-7 didymium glass wavelength accuracy calibration standard NEVER needs to be recalibrated due to material aging. Thirdly, in addition to providing wavelengths calibration picks, NSG also supply photometric absorption data for all 5 wavelengths. Lastly, for each WAV-7 Calibration Standard NSG Precision Cells is able to provide a wavelength/absorption trace-file with 0.1 nm steps upon request.
NSG Precision Cells’ WAV-7 NIST-Compliant Combined Wavelength Accuracy/Photometric Calibration Standard provides the following NIST-compliant picks' values for the wavelengths’ accuracy calibration of spectrophotometers: 329 nm, 472 nm, 512 nm, 681 nm, 875 nm. Al
