WAV-7 NIST-Compliant Combined Wavelength Accuracy/Photometric Didymium Glass Calibration Standard
Our NIST-Compliant WAV-7 Wavelength Calibration Standard is the UNIQUE product on market in its category which NEVER needs to be replaced or re-calibrated due to materiaI aging.
The WAV-7 filter allows calibration of wavelength accuracy of spectrophotometers in both the ultra-violet (UV) and visible (VIS) range as well as photometric accuracy of spectrophotometers at 5 wavelengths’ points in UV range (!).
Our Certified WAV-7 Calibration Standards are NIST- and NRC-Canada compliant and traceable.
We also hold the WAV-7 product’s NIST-compliant benchmark Calibration Certificate issued directly by the NRC Institute for National Measurement Standards, Government of Canada.
All calibration kits come with the following:
-NSG Precision Cells Unique Lifetime Warranty
-Certificate of Calibration
-Instructions on how to properly use calibration standards
Reminder: The measured wavelengths’ peaks depend, among other factors, on the user’s spectrophotometer’s slit-width (spectral band-pass). Our calibration measurements are provided with 2 nm slit-width and could also be performed, for an extra fee to be set on per-case basis, at the customer-desired slit-width(s).
We provide the following NIST-compliant picks' values for the wavelengths’ accuracy calibration of spectrophotometers:
- 329 nm
- 472 nm
- 512 nm
- 681 nm
- 875 nm
We provide NIST-compliant absorbance values for the photometric accuracy calibration of spectrophotometers at the following wavelengths:
- 270nm
- 280nm
- 300nm
- 320nm
- 340nm
Advantages of NSG WAV-7 Didymium Glass Calibration Standard:
Our WAV-7 Calibration Standard is NIST-Compliant
- Our unique materiaI-formation and nano-deposition proprietary manufacturing process assures unmatched stability of optical performance of WAV-7 Calibration Standard. WAV-7 NEVER needs to be recalibrated due to materiaI aging.
- In addition to providing wavelengths calibration picks, we also supply photometric absorption data for all 5 wavelengths of the corresponding NIST standard: 270nm, 280nm, 300nm, 320nm, and 340nm.
- For each WAV-7 Calibration Standard we provide a wavelength/absorption trace-file with 0.1 nm step
