The Holmium Oxide Glass Filter is a solid-state wavelength reference material designed for use in UV and visible spectroscopy, covering the spectral range from 240 nm to 640 nm. It contains holmium oxide embedded in a glass matrix, providing distinct absorption peaks characteristic of holmium for instrument wavelength calibration.
The filter is mounted stress-free within an anodized aluminium holder, enhancing its robustness compared to liquid reference cells. This makes it suitable for routine wavelength qualification in demanding laboratory or industrial environments. Sliding window covers protect the optical surface from damage when not in use. Each filter is supplied with an individual certification due to minor batch variations affecting peak position accuracy.
