There is a solution to every filter requirement
Optical interference filters use the interference effect to obtain spectral transmission are manufactured by depositing thin layers with different refractive indices onto a substrate.
SCHOTT offers standard and customized optical interference filters within the spectral range of 200 nm to 3,000 nm. These products are developed, designed and manufactured according to customer specifications. Interference filters offer excellent climatic resistance and extremely stable spectral characteristics with respect to temperature and humidity changes.
Our product range includes various types of optical interference filters:
Longpass and shortpass filters
NIR cut filters
Almost all inorganic glasses and glass-ceramics are suitable substrate
materials for optical filter coatings. The choice of the substrate will depend on the
specific requirements of the end product. The following materials can be coated: Specifications
The specifications listed in our 'Interference Filters and Special Filters' catalogue apply to standard interference filters; however, 95% of all for our filters are customized.
If you need assistance in determining the specifications for customized optical interference filters, please contact our sales and application engineering teams. Quality Assurance
