Product Portfolio
  • Advanced Optics

      • Optical Glass

          • High Homogeneity Glass

          • Extremely high homogeneity for large precision optics

            The superior quality of an optical material is reflected in its homogeneity and, to be even more specific, in an extremely narrow variation range for the entire piece of glass with respect to refractive index. Therefore, the optical glasses that are used in high-power laser and astronomical applications require extremely high homogeneity.

        • Optical Components

            • Aspherical Lenses


              Aspherical lenses have a complex surface profile. SCHOTT uses both CNC machining (Computerized Numerical Control) and MRF tooling (Magneto Rheological Finishing) techniques to manufacture these lenses in small and medium-sized quantities or for use in prototypes.

              Due to their unique surface structure, aspherical lenses eliminate monochromatic aberrations (e.g. spherical aberrations) and therefore deliver superior overall image quality. They are being used to 2720 multi-spherical element assemblies more and more frequently because this reduces the total weight and enables a more compact design.
            • Cylindrical Lenses


              Cylindrical lenses have a spherical radius in one direction. This enables the light to be focused in one axis. A point of light can thus be stretched into a single line.

              Cylindrical lenses can be used in a variety of different applications, including bar code scanning or laser projection, for example.
            • Spherical Lenses


              Spherical lenses are used in many different applications to collect, focus and diverge light and are often components of lens systems that perform an achromatic function.

              Achromatics consist of two or three elements of different lenses cemented together to limit the effect of spherical and chromatic aberration.
            • Prisms


              Prisms are transparent optical elements with flat polished surfaces that refract, reflect or disperse light. They can be positioned rather easily inside an optical system and offer excellent thermal stability. Total internal reflection is possible to avoid light loss in the optical path.

              Examples of Products: 
              • Right-angle prisms
              • Rhomboid prisms
              • Penta prisms
              • TIR prisms
              • Cube beamsplitters
              • Roof prisms
              • Porro prisms
            • Windows & Substrates


              Substrates are components (plano-plano parallel polished components, lenses, prisms, filters, etc.) made of different materials that serve as the base to be coated to produce products like beamsplitters, mirrors, and windows, for example.

              Windows are transparent, mostly plano-plano parallel polished and/or coated components that are used in optical systems to achieve highly-efficient, distortion-free light and perfect image transmission.

              Examples of Products:
              • Plano parallel windows
              • Protective windows
              • Laser line windows that feature an antireflective coating
              • Optical flats
              • Substrates for microlithography
              • Brewster or elliptical windows
          • Optical Filters

              • Contrast Enhancement Filters


                Contrast enhancement filters allow only certain wavelengths of light from a display device to pass through and filter out irrelevant wavelengths. The displays are thus able to achieve a higher level of contrast. Furthermore, full color displays are capable of reproducing colors more naturally.
              • Optical 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.

                SCHOTT supplies standard and customized 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.
              • NIR Cutoff Filters / Blue Filter Glass


                Used in numerous applications, NIR cutoff filters can be found just about everywhere we look in our modern lives. They are equipped to image sensors so that natural colors are produced, and they make digital cameras respond to light as our eyes do. Special NIR cutoff filters are required for the displays and operation controls (NVIS compatible equipment) of night vision systems, which are becoming more and more commonly used by police and rescue forces.
              • Optical Filter Glass


                SCHOTT Advanced Optics offers one of the world’s broadest portfolios of optical filter glasses for a full spectral solution that meets your requirements.

                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.
              • Suntanning Filters

            • IR-Materials

                • Infrared Chalcogenide Glasses


                  Infrared glasses (IRG) offer excellent transmission in the shortwave IR (SWIR), midwave IR (MWIR), and longwave (LWIR) range. Physical properties such as low dn/dT and low dispersion enable optical designers to engineer color-correcting optical systems without thermal defocusing. The IRG family of chalcogenide glasses is optimized for pairing with the family of IR glasses and other IR materials to support cost-effective and high-performance optical designs. These glasses encompass the common IR transmission bands 3 - 5 μm and 8 - 12 μm, but can transmit as low as 0.7 μm. Furthermore, the IR glass series offered by SCHOTT can be processed using conventional grinding and polishing techniques, single point diamond turning or molding to support low- to high-volume component-level manufacturing.
                • Sapphire


                  As one of the hardest, most durable and scratch-resistant materials, sapphire offers a broad transmission range from UV to mid-infrared wavelengths (250 – 5,000 nm). It is capable of withstanding extreme environmental conditions and fluctuations in temperature. SCHOTT, a sapphire glass supplier, offers sapphire in processed shapes according to customer’s specifications.

                        • Astronomy & Space

                        • REACHING FOR THE STAR

                          Every discovery starts with a cloudless night. To an astronomer, broadening horizons means reaching for the stars.

                          But if you’re spending your nights stargazing, you're happy for any help you can get. Only one thing’s better than a large telescope aperture: an even larger telescope aperture. Brown dwarves, red giants, black holes, perhaps even extraterrestrial lifeforms – what may have started as a school project today might quickly wind up as an entry in tomorrow’s history books.
                        • Industrial Equipement

                        • THE TAMING OF THE LASE

                          Set your jewels to get them seen. Or use them for something else, perhaps? Something less showy, but perhaps more useful? Monocrystals. A single crystal, industrially tamed and a kind of Philosopher’s Stone for innovation. The artificial crystals are a fascinating material for electronics. Without them, a lot of development progress could not have taken place at all. Micro-electronics and computer technology simply can’t get enough of them. Microlithography, for example, needs them to produce and process integrated circuits.

                        • MEDICINE STEP-BY-STEP

                          The goal is to heal. The next milestone is hope. Or at least quality of life. A good laugh is medicine in itself. But where laughing no longer comes easily, it’s best to turn to science. Pursuing a vision in the medical field requires the preparedness to advance in small steps. Progress in diagnosis, analysis and therapy always needs leaps in technology to change the boundary conditions. Antibody micro-arrays by SCHOTT assist science in the fight against cancer. It took a special coating to pave the way to the ground-breaking fluorescence microscopy capable of identifying biomarkers. Optical filter lenses are also used as substrates for thin-film coatings employed in interference filter production. We have 70 variants available. All of them are reliable helpers in blood testing units, gas chromatographers and waste water and combustion analysers. Along with other thin glasses, the B270® i crown glass with high transmission rate and chemical resistance is available as a glass wafer or substrate. All of them are used to make biochips. Even the longest journey can be made in many small steps.
