Holmium Oxide Standard

Holmium oxide (4%) in 10% v/v perchloric acid. For the verification of the UV-Visible spectrophotometer wavelength scale.

…stray light (200 to 700 nm), and wavelength accuracy in the UV and visible range (200 to 700 nm). The wavelength accuracy filter is made from holmium oxide and has ten NIST-certified calibration peaks. The UV photometric accuracy filter is made from didymium and has five NIST-certified calibration…
