Didymium Glass Wavelength Standard

The glass filter is mounted in an alloy holder with dimensions equivalent to a standard cuvette.  This wavelength standard is offered in two (2) product versions: CRM 150 and CA2M 752.

STRANASKA® CRM 150

  • glass equivalent to NIST SRM 2013
  • certified for absorption bands in the spectral range ~ 340 nm to 880 nm
  • one (1) spectral bandwidth (1 nm)
  • certified with routine scientific metrological rigor and traceability that is consistent with prevailing standard industry practices
  • routine uncertainty budget

STRANASKA® CA2M 752

  • enhanced version of CRM 150
  • certified for absorption bands in the spectral range ~ 340 nm to 880 nm
  • one (1) spectral bandwidth (1 nm)
  • certified wavelength values and uncertainties for absorption bands at custom spectral bandwidths available upon request
  • certified with advanced scientific metrological rigor and traceability to a holmium oxide solution intrinsic data standard
  • advanced uncertainty budget
