Interference Filters Our product range comprises different interference filter types: • andpass filters (line, band, and B broadband filters) • dge filters (long- & shortpass filters) E • Notch filters (single to tripple notch) • UG 11: UV transmissive filters withD out passband at 700 nm • ard bandpass filters H • i-line filters • ERIL linear variable filters V • V-filters: low-fluorescence, sharp K cut-on, glass-plastic laminated filters Specifications The specifications listed in our catalog apply to standard interference filters, while 95 % of filters are customized. We supply filters smaller than 1 x 1 mm to about 400 mm in diameter, depending on the interference filter specifications. Applications Interference filters are used in various applications such as: • luorescence microscopy & Raman spectroscopy F • nalytics: measurement, environmental, biotech, chemical, medical, etc. A • Semiconductor microlithography • easuring, testing, and control engineering M • ptoelectronics & telecommunication (e. g. LCD projector, bar code reader) O • ensors (industry, automotive (rain sensors), safety and monitoring systems) S • phthalmology & dentistry O • Photo finishing Substrates Almost all inorganic glasses and glass ceramics are suitable as substrate material for interference filters. The choice of substrate is depending on the specific requirements of the finished interference filter. Coatable materials are: • Optical glass • orosilicate glasses (e. g. BOROFLOAT®33) B • ptical filter glasses O • lass ceramics (ZERODUR®) G • Technical glass • Fused Silica Quality Assurance Quality control is based on statistical process control as well as on rigorous final inspection. Measurement instruments include a broad range of spectrophotometers, vision systems, beam deflection, etc. Advanced Optics SCHOTT AG Hattenbergstrasse 10 55122 Mainz Germany Phone +49 (0)6131/66-1812 Fax +49 (0)3641/2888-9047 info.optics@schott.com www.schott.com/advanced_optics Product Information Interference filters, using the interference effect to transmit or reflect certain spectral ranges of electromagnetic radiation, are produced by applying thin layers with different refractive indices on a substrate. SCHOTT supplies standard and customized interference filters within the spectral range from 200 nm to 3000 nm. Develop ent, design and m production are realized according to customers’ specifications. The coatings of the interference filters are manufactured by deposition process in high vacuum or using a Mag etron-Sputteringn Tool. The processes, ion assisted evaporation and reactive ion plating, lead to very hard and compact thin films. As a consequence, these interference filters have an excellent climatic resistance and a very stable spectral characteristics with respect to temperature and humidity changes.
