NSG's equivalent of the NIST SRM 1930 calibration reference kit for testing photometric accuracy in the VIS range (400-700nm). This kit comes with NSG's Lifetime Warranty and never requires recalibration.

This kit includes the following filters:


  • Photometric accuracy verification in the VIS range (400-700nm)

Product Specs:

  • Wavelength range: 400-700nm (this kit can be used for any wavelength within this range).
  • Tolerances: HF-0.3 (+/- 0.0020 au); HF-1.5 (+/-0.0054au); HF-2 (+/-0.0055au)
  • External dimensions of individual filters: 12.5 x 12.5 x 45.0 mm

Benefits of using NSG's Solid-State Calibration Standards:

  • Highly accurate and consistent spectrophotometer calibration every time.
  • Never has to be replaced.
  • Never has to be recalibrated if used properly.
  • Scratch-resistant coating protects optical surfaces.
  • Can be used in any spectrophotometer (with standard 12.5 x 12.5 x 45.0 mm holder)
  • Surpasses NIST-1930 requirements and tolerances
  • NIST-compliant
