INTERFERENCE AND SPECIAL FILTERS

THE RESULT OF MANY YEARS OF RESEARCH AND DEVELOPMENT

Interference band-pass filters – Individually customized interference filters
Thin film filters allow you to build solutions to meet the demands of the latest technologies and applications. We keep interference filters in popular wavelengths on stock.

 

 

KV-filters - glass-plastic laminated filters
These filters possess long-pass characteristics and therefore have very steep curves and very low inherent fluorescence, hence their suitability as fluorescence barrier filters. Their spectral properties are determined by a special plastic layer sandwiched between two polished glass plates that protect against environmental influences.


UV-broadband filters – based on UG11 with secondary pass-band blocking

The UV-broadband filter types DUG11, DUG11X and IRB are made of SCHOTT UV-transmitting filter glass UG11. Its typical secondary passband at about 720nm within the red spectral range has been blocked by means of vapour-deposited hard metal oxide layers on both sides. These oxide layers also function as a protective coating against environmental influences.
