Highly advanced interference filters for medical diagnostics now available in accordance with customer specifications
The highly advanced fluorescence and Raman filters that SCHOTT offers according to customer specifications are used in the area of medical diagnostics. The fluorescence filters for analyzing fluids are actually bandpass filters.
In fact, a microscope used to analyze fluorescent dyestuffs contains a set of components that consist of three filters which are each made up of as many as several hundred layers. Excitation bandpass filters, dichroic filters and emission bandpass filters are precisely tailored to match each other. Only then can exact diagnostic results be guaranteed. Several different types of filters are used in filters for Raman spectroscopy, including bandpass, short pass, long pass and notch filters. Monochromatic light from a laser is usually used in this diagnostic method to analyze a sample.
The high-quality filters that SCHOTT offers are also used in astronomy: steep edge and narrow-band bandpass filters with an extremely broad blocking area that ranges from the UV all the way to the near IR range. These filters are typically used to perform spectral analysis of the universe in satellites and in the instruments of ground-based telescopes.
SCHOTT also offers coatings for use in high energy lasers. Research laboratories and material processing lasers depend on them to achieve the maximum, extremely high laser damage threshold.
Broad range of product properties possible
SCHOTT offers a wide range of hard coatings, from laser and scratch-resistant, anti-reflective coatings like those that are used in the cover glasses of high-quality wrist watches to laserhard laser mirrors or dichroic filters such as beam splitters and polarizers. Furthermore, these coatings enable many other different product functions: density and climate resistance, high temperature stability, low transmission losses, better adhesion, thermal stability of spectral performance and the slightest inclusions of water inside a coating.
