Holmium Oxide Glass Filter

Holmium Oxide Glass Filter is a wavelength accuracy standard for all LAMBDA UV/Vis and UV/Vis/NIR spectrometers. The filter is mounted on a precision aluminum spring mount and ships in a re-usable, UV-protective storage container with a Certificate of Calibration.

This filter ships with the Photometric and Wavelength Accuracy Reference Standards Set (B0507805), but with this part number, it can be ordered separately as a replacement or spare filter. It requires the Single Recalibration Kit (N1010540).
