Holmium wavelength calibration standard

Description

• General description: Holmium Wavelength Calibration Standard is a high-quality secondary reference standard offered as a suitable alternative to NBS Holmium Oxide Solution (No. 2034). It is used to establish the accuracy of conventional spectrophotometers in the spectral range 240 to 650 nm. The product consists of Holmium perchlorate (15% w/v) in 10% perchloric acid.
• Application: Holmium Oxide Glass Wavelength Standards.: This article discusses the use of holmium oxide glass as a standard for calibrating the wavelength accuracy of spectrophotometers. Such standards are crucial for ensuring precise measurements in various industrial applications, including the development and testing of medical devices and energy storage solutions (Allen DW, 2007).
