The
offered Physical Vapor Deposition (PVD) materials - OXIDES are useful
as basic materials for production by thermal evaporation, deposition
by electron-beam or by ion-plasma evaporation of transparent thin-film
coatings, which improve the optical characteristics of workpieces
made of glass, quartz, single crystals, semiconductors, etc. Used
for deposition of mono- and multilayer optical coatings, they are
highly effective in ultraviolet, visible and infrared spectral regions.
Antireflective (AR) coatings reduce reflections and ghost
images while enhancing the transmission of light. This is especially
important when a large number of surfaces are used, as in microscopes,
camera lenses or endoscopes. Besides antireflective coatings, a wide
range of applications are served in the UV, visible and infrared range,
in lighting systems, laser technology, projection systems, and even
in medical applications such as mirrors, band-pass filters for information
technology, coatings for displays, and more.
The OXIDES film-forming materials are deliverable in form
of tablets or granules, based on high-pure metal compounds.
PVD processing is carried out in high vacuum at temperatures between
150 and 500 °C.
