Definitions

  • the invention relates to a method for coating glass surfaces, wherein a multi-layer system is applied.
  • Dichroic dielectric mirrors consist of several transparent layers with alternately different refractive indices on a glass substrate. They only reflect in a limited wavelength range and in a limited angle of incidence. They can be constructed in such a way that they either reflect very well only in a very narrow wavelength range ( ⁇ 99.9%) or, for example, pass the entire IR range (cold mirror in the case of halogen lamps).
  • the substrate used is also metals, plastics and even monocrystalline substances. Criteria for the choice of substrate are its machinability, thermal expansion coefficient, price and - especially at high power - the thermal conductivity. For material processing with carbon dioxide lasers, all-metal mirrors of copper are often used.
  • a mirror eg in SLR cameras, mirror galvanometers and reflector telescopes
  • the mirror layer must carry the mirror layer forward (surface mirror).
  • the mirror layer must be in In this case, it is usually protected from oxidation and mechanical damage by a thin, preferably hard, transparent cover layer.
  • Interference mirrors are often also referred to as reflection mirrors. They consist of a mirror layer provided with microscopic grooves. They are used in spectrometers and monochrometers to separate individual wavelengths.
  • Partly permeable metal layer mirrors are based on a property that already possesses uncoated glass surfaces. They are teiirefiektierend in a wide Weilenauerbe-.
  • Such semi-transparent mirrors have a reflective on a glass sheet
  • Semi-transparent mirrors are also known as "spy mirrors" or splitter mirrors and serve as beam splitters: part of the incident light is reflected, the rest is transmitted (absorption is neglected here) .
  • the respective proportions can be determined by choosing a suitable composition of the applied reflection layer.
  • Thin gold layers reflect primarily in the infrared, but are bluish in visible light.
  • Interference mirrors are always partially transparent away from their design wavelength. They carry on a glass substrate several transparent layers with alternately different refractive indices. The thickness of the layers is half the wavelength of the radiation to be reflected.
  • Interference mirrors reflect only in a limited wavelength range and in a limited angle of incidence, but achieve much higher reflectance (> 99.9%) than is possible with metal mirrors (up to 96%).
  • Interference mirrors can also be used as low-loss, partially transparent mirrors (beam splitters) and for splitting into different wavelengths or as color filters (interference filters).
