Spectrophotometer Visible Wavelength Qualification Holmium Oxide Glass Reference

The holmium glass filter produces characteristic peaks that make it suitable for use as a wavelength reference material in the UV and visible regions of the spectrum (240 nm - 640 nm).

It is accepted for this purpose by the following bodies:

  • American Society for Testing and Materials
  • Therapeutic Goods Administration (Australia)
  • British Pharmacopoeia

The spectrum shows 11 characteristic and well-defined peaks covering the wavelength range from 240 nm to 640 nm.

Approximate peak wavelength values (in nm) are: 242, 279, 288, 334, 361, 419, 446, 454, 460, 537, 638
