Our range of optical glasses includes arsenic-free N-glasses, glasses suitable for precision molding (low Tg-Glass) as well as classical glass types with lead oxide as an essential component for outstanding optical properties. In addition, we offer special versions of our glasses, e.g. high transmission glasses (HT- & HTultra-Glasses) or our high homogeneous glasses. Optical filter glass Filter glasses enable applications in analytics, photography, medical technology and laser protection. Optical filter glass is known for its selective absorption in the visible wavelength range. The optical filter glasses appear to be colored if their filter effect lies within the visible light spectrum. SCHOTT’s optical filter glasses include the following filter types in the wavelength range above 200 nm: • Bandpass filters • Longpass filters • Shortpass filters • Neutral density filters • Contrast enhancement filters • Multiband filters and • Photo filters Interference filters Interference filters that use the interference effect to obtain spectral transmission are manufactured by depositing thin layers with different refractive indices onto a substrate. These filters are used for applications in medical technology, for analytics in measurements, environmental, biotech, chemical and medical, fluorescence microsopy, and more fields. SCHOTT supplies standard and customized interference filters within the spectral range of 200 nm to 3,000 nm. Our product range comprises various types of interference filters: • Bandpass filters • Edge filters • Notch filters • DUG 11 • Hard bandpass filters • i-line filters • VERIL linear variable filters • Hard (scratch-resistant) and broadband AR coated • Beamsplitters • Neutral density filters • Mirror coatings • Black coatings
