Far-UV mirrors promise consistent performance

Starna is one of the few vendors capable of supplying far-UV mirrors with proven performance.

Starna, leading manufacturer of optical components, spectrophotometer cells and optical reference materials, has introduced new quality assurance technology in its Hainault (UK) plant to prove the reflectivity of its far-UV (vacuum-UV) mirrors.

Far-UV optics are particularly susceptible to atmospheric damage, and Starna far-UV mirrors are routinely supplied with a high reflectivity magnesium fluoride coating, whose thickness must be precisely controlled to optimise performance.

An Acton Research deep UV spectrometer is now used as a routine production QA tool on these components, and is capable of determining absolute reflectance on multiple samples in the 120-190nm region.

Starna is one of the few vendors capable of supplying far-UV mirrors with proven performance.

The company has over 30 years production experience on UV enhanced optics and use state-of-the-art production plant to supply leading instrument manufacturers and research establishments with optical components manufactured to their own specifications.

A choice of glass and quartz substrates and a variety of surface coatings are available.
