Superband calibration standard for UV/VIS/NIR photometric accuracy (200-3000nm). Optical density 2.5

We believe the Superband standards are the only ones that enable verification of photometric accuracy over the entire 200-3000nm UV/VIS/NIR range!



  • Optical density 2.5AU / transmission 0.3%
  • Expanded uncertainty: +/- 0.0090AU
  • Wavelength range: 200-3000nm - 10 calibration points
  • External diemensions: 12.5 x 12.5 x 45.0mm

Advantages of Firefly Scientific's SPB photometric accuracy filters:

  • Highly accurate and reproducible calibration of your spectrophotometer
  • Never need to be replaced
  • Never need recalibrating if handled and stored correctly
  • Scratch-resistant coating protects optical surfaces
  • Can be used in any spectrophotometer (with standard 12.5 x 12.5 x 45.0mm holder)
  • Correspond to or surpass NIST SRM 2031b requirements and tolerances
  • NIST-traceable and compliant
