The holmium oxide filter is a stable solid-state optical reference standard designed to provide precise wavelength calibration for a range of UV-Vis spectrophotometers. Manufactured with high-purity holmium oxide glass, this filter features distinct and well-defined absorption bands across the ultraviolet and visible spectral regions, making it ideal for verifying and calibrating instrument wavelength accuracy. Laboratories performing routine spectrophotometric analyses rely on this reference material to ensure consistency and compliance with regulatory standards in pharmaceutical, environmental, and materials science research.

The filter is typically used in quality assurance protocols, instrument performance validation, and compliance testing with international standards such as ISO and pharmacopoeias. Its robust construction ensures longevity and resistance to fading or photochemical degradation, supporting repeated use in demanding laboratory environments. Compatible with Agilent Cary and Varian UV-Vis systems as well as spectrophotometers from other leading manufacturers, it offers broad applicability across multiple platforms. For comprehensive instrument verification, this product can be paired with other certified reference filters, such as neutral density and didymium filters, to establish complete performance qualification. This reliable holmium oxide filter contributes to precise, traceable, and reproducible analytical results in a variety of research and quality control settings.
