Optiglass, manufacturer of Starna CRMs, is the only listed supplier of UV and visible spectrophotometry references, and produces a comprehensive range of NIST traceable references for wavelength, photometric accuracy, resolution and stray light.
A wide selection of heat-sealed liquid references covers the ultra-violet and visible spectrum, and includes new specially developed reference materials for the important far-UV region.
Traditional Didymium, Holmium Oxide and Neutral Density glass filters are also supplied.
These products also carry a lifetime guarantee.
John Hammond, Technical Manager for Analytical Products at Optiglass, explained: "The Guide 34 accreditation involved a detailed statistical analysis of the extensive stability and homogeneity data we had already accumulated on CRM's as part of our existing ISO 17025 procedures, and a formal review of all associated customer feedback activities.
As a result of this exercise we can now offer the end-user a lifetime guarantee on Starna CRM's, providing they have been used and stored correctly, and have been re-certified every two years.".
