Product Description
Holmium Glass Filter & Didynium Glass Filter - UV and Visible Wavelength with CertificateLike its liquid counterpart, the holmium glass filter produces characterisitc peaks that make it suitable for use as a wavelength reference material. As a solid material it is physically more robust than the liquid cell, and can therefore be used in a more demanding environment, providing care is still taken to avoid scratching the surface of the filter. By individually certifying each Starna Brand filter, uncertainty caused by variations in peak positions (observed from melt to melt of the glass) is significantly reduced to acceptable levels (+0.2nm).
