Schott Magnetron Sputtering Spectral range 200-300 nm
Categories: Ceramic; Glass; Optical; Filter

Material Notes: Magnetron sputtering: Applying an additional magnetic field in a sputtering machine generates a higher ion density at the sputtering target. Thus denser coatings and a higher deposition rate result in steeper filter slopes allowing extreme wavelength selection. With the customized sputtering tool different dielectric and metal coating materials can be applied without the need to open the chamber between coating runs resulting in higher design freedom for steep optical filters, consistent spectral performance for hard filter coatings, low-defect surfaces and excellent process stability. Applications: Steep filter curves can be used for long-, short-, and bandpass filters to be applied in:
  • Raman spectroscopy
  • Fluorescence excitation and emission in bio-photonic, medical, analytical and pharmaceutical applications
An additional hard coating can be applied for protection to be used in:
  • Displays with AR coating
  • Protective windows
  • Additional protection for (steep) interference filters
Advantages:
  • High signal to noise ratios
  • Steep filter edges resulting in e.g. high discrimination between close spaced emission and excitation wavelengths
  • High long time stability and durability
