Benefits of using the WAV-7 UV/VIS:

• Highly accurate and consistent spectrophotometer calibration every time

• Patented nano-deposition manufacturing process means that filters stay in spec longer.

• Scratch-resistant coating protects optical surfaces

• Can be used in any spectrophotometer (with standard 12.5 x 12.5 x 45mm holder)

• NIST-compliant

• For each WAV-7 UV/VIS we provide a wavelength & photometric trace-file with 0.1nm steps.

Included with WAV-7 UV/VIS:

• Instructions are included with every WAV-7 UV/VIS filter.

• Certificate of calibration with NIST traceability.

• Photometric and wavelength data tables are included.

All of our calibration standards are proudly made in North America.

Note: In accordance with modern metrology practices, "Data pitch (or step size) – the wavelength difference between data points - should be sufficiently close to properly define a peak. The data pitch should be less than 10% of the full width at half height (FWHH) of a spectral peak," as mentioned in the NPL REPORT DQL-AS 008 (National Physical Laboratory). Otherwise, wavelength peaks might be missed or measured with an error.
