Wavelength Standard

wavelength standardExtended range near-infrared wavelength standards are used to validate the wavelength scale of both dispersive and FT near-infrared instruments and hyperspectral cameras. Each standard is made with four components, three rare earth oxides and talc. It is a unique reflectance standard covering the entire wavelength range from 1000 nm to 2500 nm with identifiable spectral peaks. The standards are sealed and traceable to NIST SRM 1920a standards. Different sizes allow use with numerous spectroscopic instruments. Middleton Research also produces custom linear standards for calibration of line-scanning hyperspectral cameras. Contact us for more information.

The Middleton Spectral Vision 1920x is the only diffuse reflectance NIR wavelength standard studied for its thermal behavior, all analytical bands characterized with a negligible thermal gradient (Isaksson, 2003).

  • Traceable to NIST SRM-1920a
  • Meets USP wavelength calibration requirements
  • Peer-reviewed, published multi-laboratory calibration with wavelength scale accuracy better than 0.02 cm-1
  • Expedited recalibration available
