HOLMIUM OXIDE SOLUTION WAVELENGTH STANDARD

The chemical solution (4% Ho2O3 in 10% HClO4) is flame-sealed in a fused-silica cuvette of optical quality.  This wavelength standard is offered in two (2) product versions: CRM 100 and CA2M 709.

STRANASKA® CRM 100

  • patterned after NIST SRM 2034
    • fourteen (14) absorption bands
    • spectral range 240 nm to 642 nm
    • six (6) spectral bandwidths (0.1 nm, 0.3 nm, 0.5 nm, 1 nm, 2 nm and 3 nm)
    • certified wavelength values and uncertainties for absorption bands at custom spectral bandwidths available upon request
  • certified with routine scientific metrological rigor and traceability that is consistent with prevailing standard industry practices

STRANASKA® CA2M 709

  • enhanced version of NIST SRM 2034
    • nineteen (19) absorption bands
    • spectral range 240 nm to 642 nm
    • eight (8) spectral bandwidths (0.1 nm, 0.3 nm, 0.5 nm, 1.0 nm, 1.5 nm, 2.0 nm, 2.5 nm and 3.0 nm)
  • certified with advanced scientific metrological rigor and traceability to a holmium oxide solution intrinsic data standard
