STANDARDS

Certified filters, or measurement reference materials, are used as standards to test the fundamental parameters of analytical UV/VIS absorption spectrophotometers:

  • Resolution or Spectral Bandwidth
  • Stray Radiant Energy (SRE) or Stray Light
  • Wavelength Scale
  • Photometric Scale

Stranaska Metrology Laboratory (SML) does not calibrate spectrophotometers per se; instead, SML calibrates and certifies reference material filters that are then used to qualify or to evaluate the performance of spectrophotometers.
