This suite of STRANASKA® reference material artifacts are intended for the calibration and/or verification of the wavelength scales of molecular absorption spectrophotometers in the ultraviolet (UV), visible (VIS) and short-wave near infrared (SW-NIR) regions of the electromagnetic spectrum. Each filter is provided in a protective canister for storage and transportation purposes. The Certificate of Calibration for each measurement standard includes the wavelength reference values and expanded uncertainties, transmittance spectrum, calibration measurement conditions and instructional guidelines for use.

Our wavelength standards, which are offered in both CRM and CA2M brands, include the following:

  • Holmium oxide solution sealed in a fused-silica cuvette of optical quality
    • CRM 100
    • CA2M 709
    • CA2M 719
  • Holmium glass filter
    • CA2M 751
  • Didymium glass filter
    • CRM 150
    • CA2M 752
